ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(9), P. 3671 - 3679

Published: Feb. 21, 2024

CO2 electroreduction has emerged as a promising strategy for reducing emissions while simultaneously generating valuable products, particularly formic acid/formate. To further enhance the sustainability of this process, traditional oxygen evolution reaction at anode can be replaced by more interesting like glycerol oxidation to high value-added in covalorization approach. In study, effect presence bismuth (Bi) atom supplier (Bi2O3 particles) anolyte solution during electrooxidation process on platinum (Pt) electrodes coupled with formate is investigated first time, operating continuous mode single pass through reactor. The results reveal that cathode, significant HCOO– production, Faradaic efficiencies reaching 93%, and modest energy consumption 208 kW h·kmol–1 were obtained using Bi gas diffusion electrodes. On other hand, anode, Bi2O3 particles leads alteration distribution high-value-added products obtained. For instance, demonstrates remarkable dihydroxyacetone (DHA) production 283 μmol·m–2·s–1, surpassing nonmodified Pt performance system offers pathway simultaneous coproduction from both glycerol.
