Abstract

Graphite-like carbon nitride (g-C₃N₄) is an attractive photocatalyst, but its weak photo-generated carrier transport ability severely limits its application in photocatalysis. However, g-C₃N₄-based heterostructure photocatalysts have been widely investigated for their significantly enhanced photo generated electron-hole separation efficiency. In this paper, g-C₃N₄ was firstly prepared by thermal polycondensation with urea as raw material, and then the Bi₂WO₆/g-C₃N₄ heterostructure photocatalyst was prepared by hydrothermal method. The photocatalytic degradation of methyl orange by Bi₂WO₆ andg-C₃N₄ before and after composite under simulated solar radiation was studied. The results showed that the composite modification of g-C₃N₄ by Bi₂WO₆ was achieved by the hydrothermal method, and the photocatalytic performance of the heterogeneous structure photocatalyst was significantly improved compared with that of the non-composite monomer photocatalyst. The photocatalytic performance of the produced heterostructure photocatalyst is the greatest among them when the mass ratio of Bi2WO6 to g-C₃N₄ is 10:1, and the degree of methyl orange degradation reaches 90.37%after 4hof radiation.
