The electrochemical reduction of CO2 demands highly effective catalysts due to the molecule's inherent stability. Depending on the catalyst's performance and selectivity, a range of products can be generated, from simple molecules like CO or COOH to valuable organic C2 compounds. Metal-organic frameworks (MOFs), known for their exceptional CO2 capture capabilities, are potentially used as catalysts for the CO2 reduction reaction (CO2RR). In this study, we focused on evaluating the electrocatalytic performance of cadmium-modified MOF-type tin oxalates in the CO2RR process. Our findings demonstrate that incorporating cadmium as a dopant into the tin oxalate MOF not only enhances its ability to convert CO2 but also facilitates the formation of valuable organics such as formate, acetate, and isopropyl alcohol. The production of reduction products was monitored in real time using ATR-FTIR spectroscopy coupled with chronoamperometry, while structural and quantitative analysis was carried out with 1H NMR spectroscopy.
