ProdPreparation and Characterization of Ag/Zn-TiO2 Nanoparticles by Different Methods and Investigation the Effect of Synthesis Method on the Photocatalytic Activity of Ag/Zn-TiO2 Nanoparticles

Ag/Zn-TiO2 nanoparticles with various ratio moles were synthesized via two different sol-gel and hydrothermal. The prepared samples were characterized by X-ray diffraction (XRD), Transmission Electron Microscopy (TEM), Energy-Dispersive X-ray (EDX) spectroscopy,N2 adsorption-desorption isotherm, and Brunauer-Emmett-Teller (BET) analysis methods. Also,the influence of synthesis method on the crystalline structure, crystal size, surface area and photocatalytic activity of synthesized nanoparticles were investigated. Photocatalytic activity of prepared nanoparticles was investigated by photocatalytic removal of Methyl Orange (MO) under black light irradiation. Ag/Zn-TiO2 nanoparticles synthesized by hydrothermal method showed high photocatalytic activity during removal of methyl orange due to having pure anatase phase, an increase in the specific surface area, total pore volume, and the decrease in the crystallite size and agglomeration.
