Recently, electrochemical CO2 reduction attracts many interests because it is possible to reduce the amount of CO2 and simultaneously synthesize useful hydrocarbons. Of the metal catalysts for CO2 reduction, copper has been studied due to the unique property for formation of CH4 and C2H4. Furthermore, metal oxide is expected to enhance the stability and selectivity of hydrocarbon. In this study, polycrystalline copper oxide was selected as a catalyst and prepared by electrodeposition on gas diffusion electrode. It was revealed that copper oxide has higher selectivity than copper for C2H4 which is more valuable organic chemicals. Gaseous products were analyzed by GC-MS and GC equipped with a thermally conductivity detector. The samples were characterized by XRD and SEM to verify the crystallinity and morphology. |
