Structural and photocatalytic examination of CoMoO4 nanopowders synthesized by GNP method
Source abstract
Abstract
Abstract The synthesis route by solution combustion, a glycine nitrate procedure (GNP) of CoMoO 4 nanopowders by a glycine as a fuel and as a complexant was examined concerning the photocatalytic aspects and powder characteristics. The synthesized samples were investigated by differential thermal analysis (DTA), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), Ultraviolet-Visible (UV/Vis) spectroscopy and nitrogen adsorption method. In this work, we presented a simple and effective method for controlling the composition and morphology of CoMoO 4 . A single-phase α and β crystalline form of CoMoO 4 compound was confirmed by X-ray diffraction (XRD). The photocatalytic activity of CoMoO 4 nanopowders was estimated by the photocatalytic degradation of crystal violet in aqueous solution. In addition, the obtained specific CoMoO 4 nanopowder demonstrated acceptable specific surface area, which can be of particular importance for the photocatalytic processes.
