CO2 gas can be converted into suitable products, one of which is methanol. In this study, CO2 was converted into methanol by the chemical reduction method using a membrane electrode assembly (MEA) as the reaction center. MEA consists of a Nafion-117 electrolyte membrane and two electrodes in the form of cathode and anode. The cathode uses a Cu2O-ZnO/C catalyst applied to the surface of the gas …
