Abstract As a catalyst, TiO2 is nontoxic and it more cheaper cost which high-efficiency photocatalytic activity and stabilized chemical。 It has been used widely in the photocatalytic field。 Development trend has been limited, because it band gap is relatively large。 Therefore, this thesis show that TiO2 has been hydrolyzed through the Ti(SO4)2。 Then,mix up the N and the S from the Thiourea。 Meanwhile, PANI has more visible absorption, which it band gap is relatively narrow and it has chemical steadily。 The photocatalytic experiment showed that mix up PANI add N-S to TiO2 could improve photocatalytic activity under the N-S mix up the TiO2。 In conclusion, According to the experiment, The addition of a certain concentration of Fe3MoS6。 through the photocatalytic experiments showed that the addition of Fe ions and Mo ions could inhibit the recombination of TiO2 light and holes, and improve the photocatalytic activity of the composites。 we obtain the optimum proportion that all three of composite material。
The morphology, structure and chemical properties of the composites were characterized by scanning electron microscopy, X-ray diffraction, infrared and so on。
