Ti/Ni co-doped perovskite cathode with excellent catalytic activity and CO₂ chemisorption ability via nanocatalysts exsolution for solid oxide electrolysis cell.

ABSTRACT: Carbon dioxide (CO₂) gas is the main cause of global warming and has a significant effect on both climate change and human health. In this study, Ni/Ti co-doped Sr_1.95Fe_1.2Ni_0.1Ti_0.2Mo_0.5O_6-δ (SFNTM) double perovskite oxides were prepared and used as solid oxide electrolysis cell (SOEC) cathode materials for effective CO₂ reduction. Ti-doping enhances the structural stability of the cathode material and increases the oxygen vacancy concentration. After treatment in 10% H₂/Ar at 800°C, Ni nanoparticles were exsolved in situ on the SFNTM surface (Ni@SFNTM), thereby improving its chemisorption and activation capacity for CO₂. Modified by the Ti-doping and the in situ exs
