Abstract:

Ni5P4/g-C3N4 photocatalysts were synthesized by a simple calcination method with urea, phosphorus and nickel chloride. The formed heterojunction can decrease the interface resistance and photogenerate electron-hole pair recombination rate. These lead to an increase in the catalytic performance of the photocatalyst. In the photocatalytic degradation of RhB, 3NPC(mass fraction of Ni5P4: 3%) has the highest reaction rate constant, which is almost 7 times that of g-C3N4. And 3NPC also exhibits the highest photocatalytic hydrogen activity of 1013.88 μmol·g-1·h-1, which is higher than that of g-C3N4(664.38 μmol·g-1·h-1).

Key words: g-C3N4, Phosphate, Photocatalysis, Degradation, H2
