Via the hydrothermal method, one nitrogen-doped molybdate SrMoO4 photocatalyst was synthesized. In the synthesization process, further nitrogenization technique under a high-temperature NH3 atmosphere at different temperatures was also adopted. The obtained samples were characterized by x-ray diffraction (XRD), Fourier transform infrared spectroscopy, x-ray photoelectron spectroscopy (XPS), and UV-Visible absorption spectroscopy. The XRD and XPS results suggest that the SrMo(O,N)3 phase appears with the sintering temperature being 500°C. The absorption edge of SrMoO4 material is red-shifted to the visible part of the spectrum with N-doping, and then visible light photocatalytic activity is enabled. When the nitridtion temperature is up to 900°C, the photocatalytic degradation efficiency of methyl blue is increased up to 98% in 140 min. The excellent photocatalytic performance is ascribed to the following two factors induced by N doping. One is the formation of one phase SrMo(O,N)3, and the other is the formation of one heterojunction between SrMo(O,N)4 and SrMo(O,N)3. The heterojunction efficiently separates the photogenerated charge carriers and eventually reduces the recombination of the photogenerated electron-hole pairs. Moreover, one possible degradation pathway and the corresponding photocatalytic mechanism are both discussed.
