Electrochemical reduction of CO2 into valuable fuels and chemicals has become a contemporary research area, where the heterogeneous catalyst plays critical role. Metal nanoparticles supported on oxides performing as active sites electrochemical reactions have been focus intensive investigation. Here, we review with materials prepared by exsolution. The fundamental exsolution was summarized in terms mechanism models, materials, driven forces. advances exsolved used high-temperature electrolysis were catalogued tailored interfaces, synergistic effects alloy particles, phase transition, reversibility switching.

In situ exsolution of nanoparticles has been reported to be an efficient path optimize CO2 electrolysis performance. Herein, a Ce/Co co-doped SrFeO3-δ (SF) can achieve the co-exsolution CeO2 and Co–Fe alloy in 5% H2 at 800 °C. A small amount (<10%) Ce-doped SF cannot stabilize perovskite structure reducing atmosphere. Sr0.9Ce0.1Fe0.9Co0.1O3 (10Ce10CoF) Sr0.95Ce0.05Fe0.9Co0.1O3 (5Ce10CoF) as symmetric electrodes solid oxide cells showed excellent performance °C for electrolysis. The current densities with 5Ce10CoF 10Ce10CoF reached 0.98 1.30 cm–2 under bias 1.3 V after 48 h durability test electrolysis, respectively, difference, however, may due being more easily exsolved from lattice. We also investigated role oxygen vacancy (VO) determining via theoretical calculation. this work, we designed novel strategy reduction treatment outstanding
