N-doped TiO2 nanoparticle powders were prepared efficiently by the sol-gel method using triethylamine and ammonium hydroxide as composite N precursor. The as-prepared N-doped TiO2 precursor powders were calcined at 300°C in air for 3 h and subsequently annealed at 300°C in air for 2.5 h. The samples were characterized by X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy, thermo-gravimetric analysis, and X-ray photoelectron spectroscopy. The visible light photocatalytic activities of as-prepared samples were evaluated by photodecomposition of methyl orange (MO). The results show that the as-prepared samples have high visible light photocatalytic activities. Triethylamine produces the N-species doped in TiO2 lattice responsible for the high visible light photocatalytic activity. Ammonium hydroxide makes the gel of the TiO2 nanoparticles nitrided by triethylamine gelate further and facilitates significantly the centrifugation of the gel. An annealing treatment can eliminate effectively the outer N species caused by ammonium hydroxide and the surface organic residues, improve effectively crystallinity, and retain the N species caused by triethylamine.

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.
