Ni-Pd/gamma-Al2O3 Catalysts in the Hydrogenation of Levulinic Acid and Hydroxymethylfurfural towards Value Added Chemicals

gamma-Al2O3 supported Ni-Pd catalysts with different Ni:Pd ratios were studied in the hydrogenation of two industrially-relevant platform molecules derived from biomass, namely levulinic acid and hydroxymethylfurfural. The bimetallic catalysts showed better performances in both processes in comparison to the monometallic counterparts, for which a too strong interaction with the alumina support reduced the activity. The behavior of the bimetallic catalysts was dependent on the Ni:Pd ratio, and interestingly also on the targeted hydrogenation reaction. The Pd-modified Ni-rich system behaves like pure Ni catalyst, but with a strongly boosted activity due to a higher number of Ni active sites available, Pd being considered as a spectator. This high activity was manifested in the levulinic acid hydrogenation with formic acid used as an internal hydrogen source. This behavior differs from the case of the Pd-rich system modified by Ni, which displayed a much higher Pd dispersion on the support compared to the monometallic Pd catalyst. The higher availability of the Pd active sites while maintaining a high surface acidity allows the catalyst to push the HMF hydrodeoxygenation reaction forward towards the green biopolymer precursor 2,5-bis(hydroxymethyl)-tetrahydrofuran, and in consequence to strongly modify the selectivity of the reaction. In that case, residual chlorine was proposed to play a significant role, while Ni was considered as a spectator.

The Photocatalytic Degradation of 2,3,7,8-Tetrachlorodibenzo-p-Dioxin in the Presence of Silver-Titanium Based Catalysts

Polychlorinated dibenzo-p-dioxins (PCDD) are persistent toxic compounds that are ubiquitous in the environment. The photodegradation of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in the presence of silver titanium oxide (AgTi) and silver titanium doped into the Y-zeolite (AgTiY) was tested using high (254 nm) and mid (302 nm) energy UV irradiation sources. AgTi and AgTiY, both showed success in the photodegradation of 2,3,7,8-TCDD dissolved in methanol/tetrahydrofuran solution. Both catalysts were found to effectively decompose TCDD at 302 nm (lower energy) reaching in between 98-99% degradation after five hours, but AgTiY showed better performance than AgTi at 60 min reaching 91% removal. Byproducts of degradation were evaluated using Gas chromatography/mass spectrometry (GC-MS), resulting in 2,3,7-trichlorodibenzo-p-dioxin, a lower chlorinated congener and less toxic, as the main degradation product. Enzyme Linked Immunosorbent Assay (ELISA) was used to evaluate the relative toxicity of the degradation byproducts were a decrease in optical density indicated that some products of degradation could be potentially more toxic than the parent TCDD. On the other hand, a decrease in toxicity was observed for the samples with the highest 2,3,7,8-TCDD degradation, confirming that AgTiY irradiated at 302 nm is an excellent choice for degrading TCDD. This is the first study to report on the efficiency of silver titanium doped zeolites for the removal of toxic organic contaminants such as dioxins and furans from aquatic ecosystems.

Temperature Variation Enables the Design of Biobased Block Copolymers via One-Step Anionic Copolymerization

A one-pot approach for the preparation of diblock copolymers consisting of polystyrene and polymyrcene blocks is described via a temperature-induced block copolymer (BCP) formation strategy. A monomer mixture of styrene and myrcene is employed. The unreactive nature of myrcene in a polar solvent (tetrahydrofuran) at -78 degrees C enables the sole formation of active polystyrene macroinitiators, while an increase of the temperature (-38 degrees C to room temperature) leads to poly(styrene-block-myrcene) formation due to polymerization of myrcene. Well-defined BCPs featuring molar masses in the range of 44-117.2 kg mol(-1)with dispersities,(sic), of 1.09-1.21, and polymyrcene volume fractions of 30-64% are accessible. Matrix assisted laser desorption ionization-time of flight mass spectrometry measurements reveal the temperature-controlled polymyrcene block formation, while both transmission electron microscopy and small-angle X-ray scattering measurements prove the presence of clearly microphase-separated, long range-ordered domains in the block copolymers. The temperature-controlled one-pot anionic block copolymerization approach may be general for other terpene-diene monomers.

Understanding lignin micro- and nanoparticte nucleation and growth in aqueous suspensions by solvent fractionation

In recent years, there have been many advances toward developing sustainable, micro- and nanoscale materials from biobased resources such as lignin aimed at strengthening the bioeconomy. It is critical to study the factors affecting nucleation and growth mechanisms, as well as the stability of lignin micro-and nanoparticles (LPs), to further enhance the development of such materials. However, there remains a gap in the literature examining the many interactions present during and after LP formation. These interactions vary with the chemical composition and molecular weight distribution of different kraft lignin (KL) fractions. To examine the composition of different lignin fractions, KL can be fractionated using water-miscible organic solvents of different polarities such as tetrahydrofuran (THF), acetone, and ethanol. Herein, we show that the micro- and nanoparticles formed from each lignin fraction exhibit significant differences in their size (50-300 nm), particle aggregation and fusion propensity, and spherical morphology in aqueous suspensions. These differences are proposed to be a result of the solvent lignin water interactions related to molecular weight and functional groups of the lignin fractions and solvent/water polarity. Another factor affecting the nucleation and growth of LPs is the lignin concentration. The LPs formed at low lignin concentrations exhibit a larger average particle size compared to the LPs formed at higher lignin concentrations due to the aggregation and fusion of the small particles. These results will allow for a stronger foundation in understanding the nucleation and growth of LPs when attempting to develop value-added applications for kraft lignin.

A copper-catalyzed radical cascade dehydrogenative cyclization of N-tosyl-8-ethynyl-1-naphthylamines under air is described herein for the synthesis of thioazafluoranthenes. The reaction proceeds smoothly with high efficiency and a broad reaction scope. The product is indeed a new fluorophore and its photophysical properties are also investigated. Based on the results, we are pleased to find that the Stokes shift of amino-linked thioazafluoranthenes in dilute tetrahydrofuran is determined to be 143 nm (4830 cm(-1)).

Biphasic Separation Approach in the DES Biomass Fractionation Facilitates Lignin Recovery for Subsequent Valorization to Phenolics

Herein, we demonstrate a sustainable technique for quality facile lignin recovery by adopting a biphasic separation approach during the deep eutectic solvent (DES) disintegration of biomass for subsequent valorization. The tetrahydrofuran (THF)/aq NaCl combination influenced the attainment of biphasic layer separation, consequently accelerating the movement of DES-solubilized lignin to the organic phase and allowing for the easy recovery of lignin and solvents (both THF and DES) for reuse. The modified protocol facilitated similar to 32% wt lignin per wt of sawdust with a 95% purity (based on a Klason analysis), which was nearly 88% of the lignin extracted to the potential lignin of sawdust. This was achieved through the fractionation of sawdust using a choline chloride and lactic acid combination at a 1:2 molar ratio under modest thermal conditions. The obtained results were similar to 2-fold higher than those of the conventional DES protocol, employing the H2O-EtOH mixture for lignin precipitation using a similar wood substrate. All of the analytical characterization techniques, including C-13 NMR, Fourier transform infrared, gel permeation chromatography, and pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS), established the relevant structural and morphological characteristics, making the resultant lignin an adequate feedstock for the potential production of aromatic chemicals because of the dominance of the beta-O-4 content and the limited residual constituents, including sugars and silica. Upon evaluating its suitability for phenolic chemical synthesis via hydrogenolysis, a similar to 48% butylated hydroxytoluene yield was obtained as a dominant phenolic product over heterogeneous Ru@V2O5. Overall, the findings indicated that DES is proficient in fractionating lignocellulose for the entire release of lignin (>90%). The maximum recovery of the released lignin was attributed to the superlative performance of the novel THF/aq NaCl combination through the influence of molecular interactions, such as hydrogen bonding and dipole-dipole interactions between the lignin and solvent, thereby establishing an alternative trend for quality lignin extraction for deriving phenolics.

Generation of highly amenable cellulose-I beta via selective delignification of rice straw using a reusable cyclic ether-assisted deep eutectic solvent system

Cellulolytic enzymes can readily access the cellulosic component of lignocellulosic biomass after the removal of lignin during biomass pretreatment. The enzymatic hydrolysis of cellulose is necessary for generating monomeric sugars, which are then fermented into ethanol. In our study, a combination of a deep eutectic (DE) mixture (of 2-aminoethanol and tetra-n-butyl ammonium bromide) and a cyclic ether (tetrahydrofuran) was used for selective delignification of rice straw (RS) under mild conditions (100 degrees C). Pretreatment with DE-THF solvent system caused similar to 46% delignification whereas cellulose (similar to 91%) and hemicellulose (similar to 67%) recoveries remained higher. The new solvent system could be reused upto 10 subsequent cycles with the same effectivity. Interestingly, the DE-THF pretreated cellulose showed remarkable enzymatic hydrolysability, despite an increase in its crystallinity to 72.3%. Contrary to conventional pretreatments, we report for the first time that the enzymatic hydrolysis of pretreated cellulose is enhanced by the removal of lignin during DE-THF pretreatment, notwithstanding an increase in its crystallinity. The current study paves way for the development of newer strategies for biomass depolymerization with DES based solvents.

Suitability of natural rubber-based polymer electrolyte for energy storage

Electrochemical double-layer capacitor (EDLC) is an evolving member in the energy storage movement which really plays a major part in satisfying the power demands of electronic devices and systems. Today, a substantial interest is paid on environmental friendly, cheap and safe devices in the modern world. Therefore, the present study was carried out to fabricate EDLCs using natural rubber-based solid polymer electrolytes (SPEs) and exfoliated graphite electrodes which possess many of those requirements. Electrolyte was prepared using ammonium trifluoromethanesulfonate (NH4CF3SO3-NH4TF) as the salt, titanium dioxide (TiO2) as a nano additive, propylene carbonate (PC) as a solvent and 49 methyl groups grafted natural rubber (MG49) as the polymer. First, electrolytes having different salt compositions were prepared using solvent casting method. Minced NR was dissolved in tetrahydrofuran (THF) using magnetic stirring. NH4TF solution was prepared separately. MG49 and NH4TF solutions were then mixed together and stirred further. It was then poured into caped petri dish and the solvents were left to slowly evaporate. This procedure was repeated several times for different salt compositions. The optimised composition was found as NR:0.4 NH4TF (by weight basis) having a room temperature conductivity of 3.82 x 10(-4) S/cm. TiO2 and PC were added to this optimised composition to enhance the conductivity. The highest room temperature conductivity obtained was 7.10 x 10(-4) S/cm for the composition, NR:0.4 NH4TF:10%PC:10%TiO2. Exfoliated graphite electrodes were prepared using natural graphite. The characterisation of EDLC was done by using electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV) and galvanostatic charge discharge (GCD) test. Single electrode specific capacitance of the EDLC was found to be 1.68 F/g from CV test. Discharge capacitance was 0.78 F/g from the GCD test. Moreover, a good cyclic stability was observed. This novel natural rubber and natural graphite-based EDLC can be used as an energy storage device with further modifications.

Integrative platform for the selective recovery of intracellular carotenoids and lipids from Rhodotorula glutinis CCT-2186 yeast using mixtures of bio-based solvents

Natural bioactive compounds have been attracting growing interest from the industries as a greener alternative to synthetic raw materials/products. Rhodotorula glutinis yeast naturally synthesizes added value compounds such as lipids and carotenoids, commonly used for cosmetic, pharmaceutical, and food applications. R. glutinis constitutes a rigid cell-wall structure, requiring energy-saving and efficient cell disruption methods for a sustainable recovery of the intracellular compounds. A simple and ecofriendly technology using mixed bio-based solvents (biosolvents) was evaluated here as an alternative platform to permeabilize yeast cells and to improve the selective recovery of beta-carotene, torularhodin, torulene and lipids. The extraction ability of pure and solvent mixtures (methanol, ethanol, ethyl acetate, isopropanol, cyclohexane and 2-methyl tetrahydrofuran) was initially screened, demonstrating the clear impact of using mixtures to improve the extraction yields (up to three-fold increase). After identifying ethyl acetate/ethanol/water as the solvent mixture with a greater capacity to extract carotenoids and lipids, the selective recovery of carotenoids and lipids was enhanced by optimizing the solvent mixture composition ratio. Envisioning the industrial application, an integrated biosolvent-based downstream platform was designed. Two different strategies were investigated to further isolate carotenoids and lipids from R. glutinis biomass and to recycle the ethyl acetate/ethanol/water mixture: (i) precipitation using cold acetone; (ii) sequential liquid-liquid extraction. The integrated process for each strategy was compared with a conventional extraction procedure in terms of recovery efficiencies and its environmental impact. Regardless of the strategy, it is shown that the mixture of ethyl acetate, ethanol and water (15/27/58% w/w) can be reused up to three consecutive extractive cycles, ensuring high extraction efficiency yields, while decreasing the process carbon footprint by about 75% compared to the conventional method.
