Rare-earth high-entropy oxides are a new promising class of multifunctional materials characterized by their ability to stabilize complex, multi-cationic compositions into single-phase structures through configurational entropy. This feature enables fine-tuning structural properties such as oxygen vacancies, lattice distortions, and defect chemistry, making them for advanced technological applications. While initial research primarily focused on catalytic performance in energy environmental applications, recent demonstrated potential optoelectronics, photoluminescent materials, aerospace technologies. Progress synthesis techniques has provided control over particle morphology, composition, engineering, enhancing electronic, thermal, mechanical properties. exhibit tunable bandgaps, exceptional thermal stability, superior resistance phase degradation, which positions next-generation materials. Despite these advances, challenges remain scaling up production, optimizing specific understanding the fundamental mechanisms governing multifunctionality. review provides comprehensive analysis developments rare-earth relatively still underrated material future.

Solid oxide cells (SOCs) can operate efficiently in solid fuel cell (SOFC) and/or electrolysis (SOEC) modes, and are one of the most promising electrochemical devices for energy conversion storage, facilitating integration renewable energies with electric grid. However, SOC electrodes suffer performance stability issues, especially case when SOCs fueled by cheaper more available fuels such as methane natural gas. Typical Ni-YSZ cermet problems coarsening, carbon deposition, sulfur poisoning. Therefore, developing new using novel design strategies is crucial. In this review work, electrode development including situ exsolution nanoparticles, multi-elemental nanocatalysts, nanofiber materials have been reviewed summarized SOCs. Nanofiber exsolved which combine advantages a unique microstructure stable active great interest significantly contribute to high-performance
