Synthesis, Characterization,and Photocatalytic activity of Silver nanoparticledoped Phosphomolybdic acid supportedZirconia

Abstract

Abstract An ecofriendly solid acid catalyst was synthesized by impregnating phosphomolybdic acid on zirconia followed by doping with Silver nanoparticles to form composite. We report here, the synthesis, characterization and photocatalytic behavior of AgNPs doped Keggin Ions/ Zirconia which is synthesized by wet impregnation method. The resulting nanocomposite was characterized by X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR) and UV-Visible spectroscopy. The photocatalytic activity of the catalyst was evaluated for the degradation of azo dye under the Visible light irradiation. In the photoreaction study, it is found that photocatalytic activity increases by doping the noble metal silver nanoparticles on PMA/ZrO2 surface to form the composite.
