Abstract

The preparation and characterization of Pt/C and Cu2O-ZnO/C electrodes and their application for conversion of CO2into methanol by Membrane Electrode Assembly (MEA) electrochemical reduction methods has succesfully carried out. The electrodes were cast by spraying method and immerse into KHCO3electrolyte to obtain their electrochemical performance. Electrochemically active surface area of the catalyst (Electrochemical Surface Area/ECSA) of electrodes obtained from cyclic voltammetry (CV) curve indicated ECSA value on the Pt/C electrode as 378.69cm2/gand the Cu2O-ZnO/C electrodes as 209.89cm2/gwith scan rate of 50 mV/s. Electrochemical Impedance Spectroscopy (EIS) analysis was performed to obtain the conductivity value of the electrodes. The value of the electrical conductivity of the electrode with Pt/C catalyst was 0.80S/cm. The result of the conversion of CO2to methanol was measured using a methanol analyzer with maximum methanol percentage achieved at 1 M concentration as 15.75 %. As lower concentration of KHCO3(0,1M; 0,4M; 0,7M)would tend to decreased the percentages as 9%; 9.75%; 12%, whilst higher concentration as 1.3 M would obtain lowest methanol percentage as 5%.
