Direct Observation of Tantalum Nitride Photoelectrode Degradation by Environmental Transmission Electron Microscopy

Abstract Stability under realistic operating conditions remains a critical challenge for photoelectrochemical (PEC) materials in solar fuel production, where photocorrosion often leads to rapid performance degradation. In particular, the formation of insulating amorphous TaOx/Ta(...
