Abstract

Narrow-bandgap Ta₃N₅ nanorods were supported on a BN substrate to produce a composite photocatalyst using NH₄Cl-based vacuum nitridation. The charge separation efficiency of Ta₃N₅ was effectively enhanced due to electron transfer from Ta₃N₅ to the BN substrate, boosting both the photocatalytic water oxidation and Z-scheme overall water splitting reactions.
