Name: 3-Hydroxydihydrofuran-2(3H)-oneOn September 1, 2020 ,《Sorbitol electro-oxidation reaction on sub<10 nm PtAu bimetallic nanoparticles》 was published in Electrochimica Acta. The article was written by Torres-Pacheco, Luis J.; De Leon-Rodriguez, Antonio; Alvarez-Contreras, Lorena; Guerra-Balcazar, Minerva; Arjona, Noe. The article contains the following contents: Sorbitol is a highly available and functionalized polyalc., with vast industrial usages and with great potential for fuel cells application. However, few studies were done regarding its electrochem. oxidation Monometallic Au, Pt and PtAu with different compositions from Pt-rich (such as Pt85Au15) to Au-rich (Pt10Au90) nanomaterials were synthesized. Several parameters like sorbitol and KOH concentration, scan rate, charge-transfer resistance, and temperature were tested. According with the physicochem. characterization, average particle sizes from 5.6 to 6.5 nm were found for all electrocatalysts, while Pt at. percentages of 85, 60, 40, and 10% were obtained. XPS revealed shifts in Pt 4f and Au 4f core-levels related to electron d. changes by the interaction between these elements and as a result, the electrocatalytic properties for the sorbitol electrooxidation reaction (SOR) were modified. The PtAu nanomaterials presented an increase of the c.d. with the raise of the KOH and sorbitol concentrations, being Pt40Au60/C the most active electrocatalyst displaying 40 mA mg-1 at 0.1M sorbitol in 2 M KOH with an onset potential of -0.50 V vs. normal H electrode. This onset potential value was more neg. to that typically reported for other polyols like glycerol and ethylene glycol. The reaction pathway of Pt/C, Au/C and Pt40Au60/C was followed by chromatog. and spectroscopic techniques, finding that the complex surfaces of these electrocatalysts were capable to carry the SOR via several electrons (from 2 to 24 e-). In this manner, the high electrocatalytic activity of Pt40Au60/C was attributed to the electron d. changes that promote a higher electron transfer forming shorter-chain byproducts. In the part of experimental materials, we found many familiar compounds, such as 3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9Name: 3-Hydroxydihydrofuran-2(3H)-one)
3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9) is a 5-membered cyclic ester. It was obtained via tin-conversion of biomass-derived 1,3-dihydroxyacetone (DHA) and formaldehyde. And it may be employed as starting reagent in the synthesis of series of seco-pseudonucleoside synthons via aminolysis.Name: 3-Hydroxydihydrofuran-2(3H)-one
