Herein, we report a [Re(bipyridine)]-carbon hybrid material for efficient and selective CO2 to CO conversion in water. The Re catalyst was incorporated into a nanoporous colloid-imprinted carbon (CIC) powder by an electrochem. polymerization method. Uniform [Re(bipyridine)]-containing polymer films were formed on the carbon surface, where the catalyst-polymer loading could be controlled by varying the polymerization parameters. Thorough pre- and post-catalysis characterization confirmed the integrity of the [Re(bpy)] CO2 reduction catalyst. CIC|poly[Re] electrodes reduced CO2 to CO in 0.5 M CO2-saturated KHCO3 electrolyte solution at Eappl. = -0.66 V vs. reversible hydrogen electrode (RHE) (η = 550 mV), with initial Faradaic efficiencies for CO formation (FECO) between 88 and 100%. Higher catalyst loadings generally yielded higher FECO and better long-term stability under catalytic conditions, producing CO and maintaining selectivity of above 70% for a period of at least 24 h for the hybrid material with the highest [Re(bipyridine)] polymer loading. While electrochem. analyses suggested some electron and mass transport issues on shorter timescales, these were not confirmed in long-term electrolysis. Our work highlights the great applicability of (electro)polymerization techniques in combination with nanoporous CIC to prepare hybrid materials for energy conversion.2,5-Dimethoxytetrahydrofuran(cas: 696-59-3Name: 2,5-Dimethoxytetrahydrofuran) was used in this study.
2,5-Dimethoxytetrahydrofuran(cas: 696-59-3) is a member of ether. Friedel Crafts reaction, for example, adds an alkyl or acyl group to aromatic ethers when they react with an alkyl or acyl halide in the presence of a Lewis acid as a catalyst.Name: 2,5-Dimethoxytetrahydrofuran
