Abstract In order to solve the problem of easy recombination of photogenerated carriers and pollution caused by sacrificial agents in the photocatalytic cracking of red phosphorus materials, a heterostructure of crystalline red phosphorus and carbon nitride (M-CN/C-RP) was designed and constructed. The results show that this heterostructure can significantly improve the efficiency of hydrogen production by photocatalytic cracking of water, and avoid the effect of sacrificial agents on the results of photocatalytic hydrogen production. Without the addition of sacrificial agent, the photocatalytic hydrogen production rate of M-CN/C-RP with heterostructure can reach 30.7 μmol·h-1, and it has better stability and can produce hydrogen continuously within 20 h.
