Abstract
Ternary metal oxides (TMOs) with flexible band structures are of significant potential in the field of photocatalysis. The efficient utilization of renewable and green solar energy is of great importance to developing photocatalysts. To date, a wide range of TMOs systems has been developed as photocatalysts for water and air purification, but their practical applications in visible light-assisted chemical reactions are hindered mainly by its poor visible light absorption capacity. Introduction of N atoms into TMOs can narrow the band-gap energy to a lower value, enhance the absorption of visible light and suppress the recombination rate of photogenerated electrons and holes, thus improving the photocatalytic performance. This review summarizes the recent research on N-modified TMOs, including the influence of N doping amounts, N doping sites, and N-induced phase transformation. The introduced N greatly tuned the optical properties, electronic structure, and photocatalytic activity of the TMOs. The optimal N concentration and the influence of N doping sites are investigated. The substitutional N and interstitial N contributed differently to the band gap and electron transport. The introduced N can tune the vacancies in TMOs due to the charge compensation, which is vital for inducing different activity and selectivity. The topochemical ammonolysis process can convert TMOs to oxynitride with visible light absorption. By altering the band structures, these oxynitride materials showed enhanced photocatalytic activity. This review provides an overview of recent advances in N-doped TMOs and oxynitrides derived from TMOs as photocatalysts for environmental applications, as well as some relevant pointers for future burgeoning research development.

Abstract
A high-performance and novel photocatalyst of BiVO4-reduced Graphene Oxide (BiVO4-rGO) nanocomposite was prepared by a facile hydrothermal method. The photocatalyst was characterized by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, transmission electronic microscopy, UV-Vis diffusion reflectance spectroscopy, photoluminescence spectroscopy and UV-Vis adsorption spectroscopy, respectively. The visible-light photocatalytic activity was evaluated by oxidation of methyl orange (MO) under simulated sunlight irradiation. The results show that the BiVO4-rGO nanocomposites exhibit enhanced photocatalytic performance for the degradation of MO with a maximum removal rate of 98.95% under visible light irradiation as compared with pure BiVO4 (57.55%) due to the increased light absorption intensity and the degradation of electron-hole pair recombination in BiVO4 with the introduction of the rGO.
