Solution combustion synthesis of β-Cu2V2O7 nanoparticles: photocatalytic degradation of crystal violet under UV and visible light illumination

Abstract

β-Cu2V2O7 nanoparticles were prepared using a solution-combustion method using two different fuels, which are: Urea and Glycine. The as-prepared catalysts were characterized using X-ray diffraction, Fourier transform infrared spectra, scanning electron microscopy, Brunauer–Emmett–Teller Method, and UV–Vis diffusive reflectance spectroscopy. The photocatalytic activity of copper vanadate was investigated by degradation of cationic dye crystal violet in an aqueous solution under UV and visible light irradiation. The effect of selected parameters such as catalyst mass, dye concentration, and solution pH on the catalytic performances has been discussed. On the other hand, the reuse tests of β-Cu2V2O7 displayed high-performance stability after five cycles.
