Abstract
Solar‐driven reduction of dinitrogen (N 2 ) to ammonia (NH 3 ) is severely hampered by the kinetically complex and energetically challenging multielectron reaction. Oxygen vacancies (OVs) with abundant localized electrons on the surface of bismuth oxybromide‐based semiconductors are demonstrated to have the ability to capture and activate N 2 , providing an alternative pathway to overcome such limitations. However, bismuth oxybromide materials are susceptible to photocorrosion, and the surface OVs are easily oxidized and therefore lose their activities. For realistic photocatalytic N 2 fixation, fabricating and enhancing the stability of sustainable OVs on semiconductors is indispensable. This study shows the…
