- Abstract
Utilizing non grid connected electricity for CO2 conversion and reuse is one of the promising approaches in the context of “dual carbon”. In order to achieve a wide and adjustable proportion of syngas via CO2 reduction, synergistic catalytic system of Cu1Iny alloy and PV2MoW9 were designed and constructed. Among alloy series of Cu1Iny, Cu1In3 exhibits the optimal CO2 electrocatalytic activity, achieving a high CO Faraday efficiency of 95.3% under an applied voltage of -0.6 V and a stable duration of up to 53 h. Further experimental analysis and theoretical studies indicated that copper-indium alloy weakens the binding between the intermediate *CO and the catalyst, accelerates the process of *CO desorption into CO, and thus improves the selectivity of CO. In this system, the CO2 reduction process is as follows: CO2 → *CO2-2 → *COOH→ *CO →CO.
