Explores CO2 electrolysis performance and carbon deposition suppression using a nickel-copper alloy in SOEC, suggesting an innovative approach to enhance efficiency.
In SOEC CO2 electrolysis, carbon deposition occurs depending on the conditions, so it is necessary to suppress it. In this study, we will use a Ni-Cu alloy instead of Ni, which is used in SOEC electrodes, to clarify the CO2 electrolysis performance and carbon deposition characteristics. Furthermore, we use DFT (Density Functional Theory) calculations to model carbon deposition in CO₂ electrolysis and clarify the mechanism of carbon deposition suppression through electrode alloying.
