ABSTRACT:
In order to search for an efficient photocatalysts working under visible light illumination, in this present work the effect of iron and copper (Fe, Cu) codoping on the NiMoO4 nanoflakes prepared by coprecipitation method using nickel chloride, ammonium molybdate, ferric chloride and copper nitrate as precursors was studied. The structure, morphology and optical properties were investigated by means of X-ray diffraction (XRD), Scanning electron microscopy (SEM), UV-Vis diffuse reflectance spectroscopy (UV-vis DRS), Fourier transform infrared spectroscopy (FTIR) and energy dispersive X-ray analysis (EDX). The DRS results indicated that the band gap of codoped photocatalysts is smaller than undoped NiMoO4 and there is a shift in absorption band towards visible light irrradiation. The photocatalytic efficiency of synthesized catalysts was evaluated by the degradation of methylene blue (MB) in aqueous solution under visible light irradiation. When 0.14 g/L of NiMoO4 nanoflakes was used the degradation of MB exceeds 98% under visible light irradiation for 180 min with a dye concentration of 10 µM. The degradation results revealed that the nanoflakes of NiMoO4 codoped with Fe and Cu shows a better synergistic effect, which significantly increased photocatalytic activity of NiMoO4 nanoflakes.
