In recent years, rising emissions of CO2 in the atmosphere have become an increasing concern. By using the abundant renewable solar energy, CO2 can be converted into valuable fuel products. Since most renewable energy can be stored in electricity which can be an energy source for CO2 reduction, the electrochemical conversion of CO2 can be promising methods for CO2 conversion. Recent works have shown various approaches to electroreduction. Still, the selectivity of hydrocarbon is still very low and high overpotential is required to convert the CO2. Here in, we propose a novel approach which is to use copper and iron bimetallic particle. Since iron has high binding energy with CO and O, it is easy to further react spontaneously having higher selectivity with methane. And copper is a well known catalyst for converting hydrocarbons from CO2. By alloying, we can expect the significant quantities of hydrocarbons from CO2 with tuning the binding strength for reduction. |
