“…It is also recognized as a promising fuel with high hydrogen content (17.6 wt %) and good portability . More than 100 million tons of NH 3 is produced each year by the traditional Haber–Bosch method. − However, it is energy-consuming and environmentally polluting because it requires H 2 , and the reaction between N 2 and H 2 has to proceed under harsh conditions of 15–25 MPa and over 673 K . Accordingly, artificial NH 3 production in mild conditions has been brought under the spotlight. , Photocatalytic nitrogen (N 2 ) fixation is a potential alternative approach to synthesize NH 3 from abundant N 2 and H 2 O driven by solar light .…”

Photocatalytic conversion of nitrogen (N 2 ) to ammonia (NH 3 ) requires strong binding of N 2 onto the catalyst surface and the generation of photoexcited electrons to activate the NN bond. In this study, Fe is doped into BiOBr nanosheets, where the photoexcited electrons have enough energy to break the NN bond. The presence of Fe induces the formation of oxygen vacancies (OVs) in its vicinity, making it a photoexcited electronrich region. The reduced Fe species effectively donates its available 3d orbital electron into the π N−N antibonding orbital to activate the adsorbed N 2 . With Fe as the active site, the N 2 fixation rate of Fe-doped BiOBr is enhanced by eight times. This work provides a sustainable alternative for N 2 photofixation and strategies for the catalyst design.
