Reaction mechanism of photocatalysis enhanced by photosensitizer was probed. The relationships between the composition of heterogeneous photocatalyst, the starting concentration of BPB, amount of photocatalyst, pH, amount of H2O2, illumination time and the decoloring rate of BPB were discussed. The results show that the decoloring rate of BPB can reach 99.1% by using WO3/α-FeaO3 as heterogeneous photocatalyst, with the composition of m（WO3）：m（α-Fe2O3 ）=3：1, the initial concentration of BPB = 15mg/L, the amount of catalyst = 0.300 g, pH= 6.3, the amount of H2O2 =0.2 mL, and the illumination time = 6 h.展开更多
