Abstract

The sol-gel approach was employed to synthesize silver-doped CeO2 nanoparticles exhibiting superior photocatalytic activity under solar light irradiation. The produced catalysts were characterized using techniques such as Fourier transform infrared spectrophotometer (FTIR), X-ray powder diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), Dynamic light scattering (DLS) and UV-vis spectrometer. These approaches were also usefulness for analyzing the absorption spectra and the concentration of azo dyes in water at variance of concentrations during the photodegradation experiment. Research results indicated that anatase phase nanoparticles of pure CeO2 and silver (Ag) doped CeO2 have crystallite sizes that range between 15 and 18 nm. The doping was found that Ag/ CeO2 catalyst enhance the performance and light absorption capabilities towards nanoparticles as compared to pure CeO2. Ag/CeO2 nanoparticles are an attractive option for photocatalytic purification of other organic-based wastewater exposed to sun light because of their significant photocatalytic efficacy in visible light, deep catalytic constancy, and reusability for dye photocatalysis.
