CO2 can be converted into useful chemical species via electrolysis, especially when combined with electrochemical water splitting. It is a promising way to reduce global CO2 emission and to produce synthesized fuel. Many transition metals have been introduced as catalyst for the conversion of CO2 to carbon monoxide, formic acid, syngas, or further reduced products, and for the water splitting to hydrogen gas. Mostly, single metal catalyst is applied to the conversion reaction. However, it has been known that the conversion efficiency and the product selectivity could not meet the requirement yet. In this study, we introduce a low-temperature electrochemical reduction of CO2 and water to such hydrogen carbon fuels as syngas, formic acid by using transition metal alloy catalysts. In order to achieve this, the electrochemical cell embedded with a proton exchange membrane and the in-situ gas chromatography technology were employed. |
