Ni-based Bimetallic Electrode in Solid Oxide Electrolyzer Cell for High Temperature Co-electrolysis |
| 초록 |
As an increase in oil price and the depletion of oil reserves, fossil fuel-based energy production will not be able to satisfy the constantly increasing energy demand. Instead, The electrolysis of steam/carbon dioxide (co-electrolysis) can produce syngas which can be converted to produce fuels that do not need to modify the existing infrastructure and reduce the usage of fossil fuels as well as the emission of greenhouse gases. In solid oxide electrolyzer cells (SOEC) electrode, H2O and CO2 are co-electrolyzed and CO2 is additionally converted into CO through reverse-water gas shift (RWGS) reaction. Therefore, it is necessary to scrutinize the three reactions to precisely explore SOEC electrode catalysts. In this study, we firstly performed the computational screening of bimetallic alloys using density functional theory (DFT) and microkinetic analysis. Based on the results, several candidates of promising bimetallic catalysts were selected. We further investigated the mechanism of RWGS reaction on Ni-based alloy materials. Our study will contribute to design SOEC catalysts by understanding the relationship between electrochemical and thermochemical reaction. |
