Title: Design and synthesis of perovskite oxide based hetero-structural cathodic catalysts for reversible CO-CO2 conversion in solid oxide cells

Abstract:

Efficient utilization of carbon dioxide is an important technical path to achieve the carbon emission peaks and carbon neutrality "double carbon" goal. Solid oxide electrolytic cells (SOECs) have high energy conversion efficiency and high thermodynamic power and are an important means of CO2 utilization and renewable energy storage. However, the linear molecules and large double-bond energy of CO2 urgently require highly active cathode materials. Although the traditional nickel-yttria-stabilized zirconia (Ni-YSZ) ceramic electrolytic cell has excellent electrolytic performance, this metal-cermet-based SOECs has some fatal defects such as carbon deposition and oxidation of nickel metal particles. Perovskite oxides with ion-electron mixed conductivity have shown the potential to replace Ni-YSZ cathodes due to their excellent redox stability and good anti-carbon deposition ability, but their catalytic performance still has not reached the basic level of nickel-based cathode. In this work, We will present our several modification strategies for improving the catalytic performance of perovskite oxides in terms of the primary CO2 reduction process at the elevated temperature
