Cation is essential for stabilizing CO2<\/sub> adsorption & conversion to CO.<\/figcaption><\/figure>\n<\/div>\n\n\n

We have uncovered a novel mechanism for CO\u2082 electroreduction (CO\u2082RR) to Formate on bismuth electrodes, which does not require CO\u2082 adsorption on the electrode surface. We also demonstrated the ability to control CO\u2082RR selectivity (Formate vs. CO) via cation in electrolyte. Notably, the presence of non-metal cations, such as CH\u2083NH\u2083\u207a, enhances CO production as compared to metal cations. The newly discovered reaction mechanism reshapes our understanding of CO\u2082RR on Bismuth electrodes. By revealing how non-metal cations influence CO\u2082RR, this finding aids the design of microenvironments to optimize electrocatalytic processes.<\/p>\n\n\n\n
