Photocatalytic Nitrogen Reduction: Challenging Materials with Reaction Engineering

Ammonia is not only the most important chemical for fertilizer production, it has also gained much interest as a future hydrogen storage material. Besides well-known Haber–Bosch process to generate ammonia from elemental sources, new ways convert nitrogen into have been investigated in last decade decentralized including electrocatalytic and photocatalytic approaches. However, photocatalysis particular suffers stagnating materials development unstandardized reaction conditions. In this Review, we shine light on recent engineering results reduction, putting an emphasis need connect activity of reported together with detailed conditions efficiencies. Photocatalytic reduction emerging field that will certainly gain significant sustainable pathway green ammonia. The strongly benefit joint efforts strong interactions between chemists, physicists engineers at fundamental level.
