红磷/氮化碳异质结构建及光催化全解水应用

摘要针对红磷材料在光催化裂解水反应中存在的光生载流子易复合和牺牲剂带来的污染问题,设计构建了一种晶型红磷与氮化碳的异质结构(M-CN/C-RP)。结果表明这种异质结构能够显著提升光催化裂解水制氢效果,并且避免了牺牲剂对光催化制氢结果的影响。在不添加牺牲剂的前提下,具有异质结构的M-CN/C-RP的光催化产氢率可达30.7 μmol·h^-1,且具有更好的稳定性,在20 h内能够持续产氢。

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.

Keywords： crystal red phosphorus heterostructure photocatalytic cracking of water to produce hydrogen
