K2HPO4-mediated Photocatalytic H2 Production over NiCoP/RP Heterojunction
文献摘要：
In this work, bimetallic NiCoP nanoparticles (NPs) were firstly prepared by a solvothermal method using red phosphorus (RP) as P source, and it was combined with RP nanosheets via a physical grinding process. Investigation indicates that NiCoP has better charge transfer ability and faster H2 releasing kinetics than the corresponding single metal phosphides alone. 6 wt％ NiCoP/RP exhibits an excellent H2 evolution activity in 20 vol.％ triethanol-amine/water solution under a 300W Xe-lamp irradiation, and the corresponding H2 production rate is 1535.6 μmol·g-1·h-1, which is 7.4, 3.2 and 2.6 times higher than those of pure RP, 6 wt％ Co2P/RP and 6 wt％ Ni2P/RP, respectively. In addition, we demonstrate that K2HPO4 can further enhancethe H2 evolution kinetics by inducing a new H+ reduction path, when appropriate K2HPO4 is introduced into the reaction solution. The H2 produc-tion rate of 6 wt％ NiCoP/RP is boosted from 1535.6 to 2793.9 μmol·g-1·h-1 due to the easier combination between H+ and electrons with the assistance of HPO42-. It is 13.4 times higher than that of pure RP. This work demonstrates that bimetallic phosphides with suitable electrolytes can greatly enhance the photocatalytic H2 evolution efficiency.
