Since photocatalytic N-2 to NH3 is a kinetically complex and multielectron reaction, designing efficient materials to fix N-2 is highly essential. Herein, we reported that simultaneously introducing oxygen vacancy and doping Fe into BiOCl nanosheets (NSs) can greatly boost the photocatalytic N-2 fixation. BiOCl NSs-Fe-5% exhibit the maximum NH3 generation rate of 1.022 mmol g(-1) h(-1) and durable stability after successive cycling, being one of the best photocatalysts for N-2 fixation. This work demonstrates a promising strategy to design efficient photocatalysts for N-2 fixation, holding great significance for extensions to other material systems.
