Testing the effect of Polytetrafluoroethylene (PTFE) on the electrode catalyst layer on methanol production as a result of CO2 conversion by electrochemical reduction has been carried out. This study used PTFE as a hydrophobic substance with varying contents (10wt%, 15wt%, 20wt%, and 25wt%) in electrodes with Cu2O-ZnO/C (cathode) and Pt/C (anode) catalysts. The electrodes were 7.5 x 7.5 cm in size and flanked the nafion electrolyte membrane to form MEA as a medium for converting CO2 to methanol. The CO2 conversion process is carried out at a CO2 flow rate of 160 mL/minute, and the source of electrical energy is obtained from a power supply at a voltage of 1.8 V. The results of electrode characterization using the SEM-EDX method revealed that the cathode had a higher Cu content with a 15wt% PTFE content of 9% and the anode had a higher Pt content with a 20wt% PTFE content of 27.2%. The highest cathode ECSA value from CV measurements was 16,924.89 cm2/g at the cathode with 15wt% PTFE content, and the highest ECSA value at the anode was 103,732 cm2/g with 10wt% PTFE content. Meanwhile, the results of the electrochemical impedance spectroscopy (EIS) analysis showed that the highest electrical conductivity value of 15.48371 S/cm was found at the cathode with 15wt% PTFE content and 31.55684 S/cm at the anode with 10wt% PTFE content. The lowest current obtained in the CO2 to methanol conversion process was found in MEA with 15wt% PTFE Cu2O-ZnO/C (cathode) and 10wt% PTFE Pt/C (anode), with the highest percentage of methanol produced at 16.2% b/v (without distillation process).
