Abstract The development of metal‐free photocatalysts with high efficiency, stability, and broadband solar absorption is a major challenge to realize green and sustainable chemical development. Recently, metal‐free nanohybrids (BP/CN) composed of black phosphorus (BP) and polymeric carbon nitride (CN) are emerged as photocatalytic hybrids with broadband light‐harvesting capabilities and higher photocatalytic performance. Herein, the latest progress of BP/CN hybrids for multifarious photoredox reactions is summarized. The different heterojunction types of BP/CN hybrid photocatalysts, including type I, type II, and multicomponent heterojunctions, are illustrated. Furthermore, the relevant applications of BP/CN hybrid photocatalysts for photocatalytic water splitting, CO 2 photoreduction, N 2 fixation, H 2 O 2 production, pollutant decomposition, and bacterial inactivation are discussed. An overview of the challenge in this area and the directions for the future is presented.
