Mechanistic routes toward C3 products in copper-catalysed CO2 electroreduction

Sergio Pablo-Garcia et al.

Summary: The study investigates the electrocatalytic CO2 reduction reaction powered by renewable electricity, finding significant production of ethylene and ethanol but absence of propylene on Cu-based catalysts, attributing it to the unfavorable formation of allyl alkoxy (CH2CHCH2O) as confirmed experimentally. This work paves the way for tailoring selective routes towards C-3 products via eCO(2)R.

Tuning the Selectivity of Liquid Products of CO2RR by Cu-Ag Alloying

Yanzhi Xu et al.

Summary: The combination of Cu and Ag can regulate the CO2 reduction products by controlling the surface active sites. In this study, CuAg films with uniform distribution and controllable stoichiometry were synthesized using E-beam evaporation to investigate the reaction mechanism of CuAg catalysts for electrochemical CO2 reduction. The results show that the introduction of Ag can enhance the absorbed *CO and *OCCO intermediates and suppress the formation of O-C-O intermediates.

The mechanism for acetate formation in electrochemical CO(2) reduction on Cu: selectivity with potential, pH, and nanostructuring

Hendrik H. Heenen et al.

Summary: Nanostructured Cu catalysts have been found to enhance the selectivities and geometric activities for high value C-C coupled products in electrochemical CO(2) reduction reaction. The selectivity mechanism for acetate formation has been elucidated through ab initio simulations, kinetic-transport model, and loading dependent experiments, indicating that the selectivity is influenced by variations in electrolyte pH and local mass transport properties rather than Cu's intrinsic activity.
