Abstract The PbSiO3 nanoparticles were synthesized by the sol-gel route in the presence of proteins as a green capping agent. The proteins such as creatine, albumin, and casein were used to the preparation of PbSiO3 nanoparticles, for the first time. The effects of various parameters such as the molar ratio of the precursors, type of capping agent, and calcination time were evaluated on the size, morphology, and uniformity of samples. The prepared products were characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectra, energy dispersive X-ray microanalysis (EDX), scanning electron microscopy (SEM), and UV–Vis diffuse absorption spectroscopy (DRS). The photocatalytic performance of PbSiO3 nanoparticles was investigated via degradation of Reactive Yellow 84 and Reactive Red 120 in aqueous solution under UV light irradiation. Also, the cyclic voltammetry analysis of PbSiO3 nanoparticles was studied.
