Title
Studies on phase formation temperature and photocatalytic properties of nano-sized solid solution of nickel molybdate and chromium–phosphate (NixCr1−xMoxP1−xO4)
Abstract

The photocatalytic activity of various proportions of nickel–chromium–molybdenum–phosphorous (NixCr1−xMoxP1−xO4) oxides in the oxidation of thymol blue at pH 8.001 under both UV and visible light has been examined. The nano-size different compositions of NixCr1−xMoxP1−xO4 (where x = 0.1, 0.2, 0.3 and 0.4) photocatalyst were prepared by chemical solution decomposition (CSD) method and characterized with X-ray diffraction (XRD), UV–vis spectroscopy, Transmission Electron microscopy (TEM), specific surface area (Brunauer–Emmett–Teller (BET)), X-ray photoelectron spectroscopy (XPS) and ICP analysis. The variations of phase separation temperature with respect to the amount of different constituents have been studied. The average particle size of NixCr1−xMoxP1−xO4 (x = 0.1) was found to be 55 ± 10 nm measured from Transmission Electron microscopy (TEM) and specific surface area (BET) is found to be ∼72.85 m2/g.

Graphical abstractThe nano-sized NixCr1−xMoxP1−xO4 was synthesized by CSD method and photocatalytic activity was investigated. The average particle size of NixCr1−xMoxP1−xO4 (x = 0.1) was found to be 55 ± 10 nm and it has effective surface area is ∼72.85 m2/g. It is showed the highest photocatalytic activity compared other mixed oxides due to small particle size and high surface area.Figure optionsDownload full-size imageDownload as PowerPoint slide
