Regulating d-band center and d-p orbital alignment to enhance K 2 NiF 4 -type cathode performance for protonic ceramic fuel cells

Abstract Regulating the transition-metal d-band center and metal-oxygen orbital alignment represents a potentially useful approach to improve cathodic oxygen reduction reaction (ORR) kinetics in protonic ceramic fuel cells (PCFCs). Herein, K2NiF4-type La0.5Sr1.5MnO4+δ (LSMO) and...
