Surface Alloying Effects of Metal Catalysts for Carbon Dioxide Electrochemical Reduction |
| 초록 |
Thermal reduction of CO (Fischer-Tropsch synthesis) using H2 converts synthesis gas (CO+H2) into hydrocarbon based valuable chemicals and liquid fuels. Electrochemical reduction of CO2 using electrical energy from wind or solar is a renewable method of producing synthesis gas (CO+H2). Catalysts that can selectively reduce CO2 into CO by consuming less electrical energy is a key to realizing CO2 based energy utilization processes. Surface alloying is a preferred route for harnessing catalytic surfaces into the desired direction. In this work, we apply density-functional theory calculations on the selected Au/Pd(111) surface alloy models and investigate how the bimetallic combination of Au and Pd is associated with the catalytic activity and selectivity of the conversion of CO2 to CO. Subsequent examination of surface electronic structures provides a theoretical support to the direct correlation between the modified surface electronic structures and the promoted selective synthesis gas production capabilities. |
