Effect of Milling Time and PCA on Electrode Properties of Cu2O-ZnO/C Catalyst Alloy used on Electrochemical Reduction Method of CO2

Carbon dioxide is one of the greenhouse gases that cause climate change, thus effort for reducing concentration CO2 necessary, example through conversion CO2. The into methanol plays important role, because in addition to gas, it also creating a future energy carrier needed fuel cell technology. One methods electrolysis method using MEA. electrochemical this study used Cu2O-ZnO/C composite catalyst made by milling at various times, as well effect PCA utilization. catalysts were characterized Particle Size Analyzer (PSA), Brunauer-Emmett-Teller (BET), Cyclic Voltammetry (CV), Electrochemical Impedance Spectroscopy (EIS) and SEM-EDX analysis. results PSA BET characterization showed longer time, smaller particle size higher relative surface area. use increased unoxidized Cu content indicated results. Based on CV analysis, has largest ECSA (Electrochemical area) value milled time three hours.
