A reactive-group guided approach is taken to synthesize atomically dispersed Ni catalysts on red phosphorus. The advanced system consists of Janus single-atom Ni sites: P−Ni for water reduction and P−O−Ni for water oxidation, leading to the efficient separation of electron-hole pairs and overall improved photocatalytic water splitting activity.
