Facile Preparation of ZnO Nanoparticles and Ag/ZnO Nanocomposite and Their Photocatalytic Activities under Visible Light

Abstract: Zinc oxide (ZnO) has been known as an excellent photocatalyst for the degradation of a variety of organic pollutants under UV irradiation. This work describes a synthesis of ZnO nanoparticles via a facile precipitation method, and Ag was doped into Ag/ZnO nanocomposite to improve the photocatalytic degradation of BPA under visible light irradiation. The obtained ZnO nanoparticles were 20 nm in size and had a relatively high surface area and pore volume, 26.2 m2/g and 0.48 cm3/g, respectively. The deposition of… Show more

“…The characteristic peaks at 630, 572, and 547 cm −1 become stronger, indicating the formation of Zn-O stretching vibration of N-ZnO, RF-ZnO, and R-ZnO samples, respectively. The shift and change of intensity of peaks could be assigned to the change in the lattice parameter, and due to the change in crystallite size of ZnO samples otherwise [ 11 ]. However, for the CF-ZnO sample, the peaks at about 650–500 cm −1 are relatively weak and not shown in the FT-IR spectrum.…”
