Hydrogen energy from water splitting is considered the highly anticipated modern resource; however, storage and transportation require complex high‐cost facilities, which argue about efficiency of hydrogen fuel compared to conventional fuels. Thereby, ammonia (NH 3 ), a liquid at ambient conditions, promises lower cost transportation, but production imposes difficulties with selectivity over several products and, notably, evolution reaction. Among methods combining advantages electrochemical photocatalytic properties, photoelectrochemical (PEC) method destined improve N 2 reduction reaction (NRR). Because multistep NRR process, enormous negative potentials, poor kinetics, activity are severely compromised. Therefore, Mo‐ Bi‐based catalysts rationally developed promote processes. Combining benefits result in effective PEC activity. This review predicted emphasize role characteristics value Mo Bi raising ammonia's selectivity.
