Highlights: • Synthesis of CoMoO{sub 4} nanoparticles in a simple, quick, and inexpensive way, by using a glycine nitrate procedure (GNP). • Two different crystal structures of CoMoO{sub 4}, α and β, was confirmed by X-ray diffraction. • BET analysis confirmed significant specific surface areas of CoMoO{sub 4} nanopowder. • CoMoO{sub 4} nanopowders can be promising solutions in photocatalytic processes toward green chemistry and sustainable development. - Abstract: The synthesis route by solution combustion, a glycine nitrate procedure (GNP) of CoMoO{sub 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{sub 4}. A single-phase α and β crystalline form of CoMoO{sub 4} compound was confirmed by X-ray diffraction (XRD). The photocatalytic activity of CoMoO{sub 4} nanopowders was estimated by the photocatalytic degradation of crystal violet in aqueous solution. In addition, the obtained specific CoMoO{sub 4} nanopowder demonstrated acceptable specific surface area, which can be of particular importance for the photocatalytic processes.
