Conversion of Carbon Dioxide into Methanol with Cu2O/C and Cu2O-ZnO/C Catalysts with Varying Electrical Voltage and Reaction Time is carried out using MEA consisting of an proton exchange membrane and electrodes. The electrodes were characterized using the Scanning Electron Microscope - Energy Dispersive X-Ray (SEM-EDX) method to show the morphology, electrode thickness and Cu content contained…
