The synthesis of g-C3N4/Bi2WO6composite materials with varying the g-C3N4content was reported in this investigation. The composite samples were characterized by various techniques. The photocatalytic activity of the g-C3N4/Bi2WO6products has been investigated by the degradation of methyl orange dye under visible light irradiation. The UV-vis absorption spectra show that the absorption edge of the composite sample shifts to longer wavelengths with increasing the doping amount of g-C3N4. It is revealed that the g-C3N4/Bi2WO6composite photocatalysts exhibit remarkably enhanced photocatalytic performance for the degradation of methyl orange. The high visible light photocatalytic activity of g-C3N4/Bi2WO6can be attributed to the efficient transfer and separation of charge carriers in the interface between g-C3N4and Bi2WO6particles.

The visible-light photocatalytic activity of titanate nanotubes (TiNTs) sensitized by 5,10,15,20-tetraphenylporphyrin (TPP), 5,10,15,20-tetraphenylporphyrin manganese (MnTPP), 5,10,15,20-tetraphenylporphyrin nickel (NiTPP) and 5,10,15,20-tetraphenylporphyrin zinc (ZnTPP), respectively, was investigated by the photocatalytic degradation of methyl orange (MO) as a probe reaction. The results showed that the central ions of porphyrins had an important influence on the photocatalytic activity of the samples. The activity was in the order of TiNTs-ZnTPP > TiNTs-TPP > TiNTs-NiTPP > TiNTs-MnTPP. Combined the result of absorption spectra with that of fluorescence spectra, it was demonstrated that various visible-light absorption and photoelectron transfer caused by the central ions of porphyrins were the decisive factor for the visible-light photocatalytic activity of the sensitized TiNTs.

A new visible-light-driven plasmonic photocatalyst Ag/AgCl/TiO2-XCX was prepared by a two-step synthesis process. The bandgap of the synthesized sample was 2.87 eV. In the degradation of methyl orange (MO) solution under the visible light (l>420 nm), the Ag/AgCl/TiO2-X CX shows higher photocatalytic activity than TiO2-X C X . The apparent ratio constant (kapp) value of Ag/AgCl/TiO2-XCX was about 9.7 times that TiO2-XCX.
