Synthesis of polypyrrole@ZrO2/Ag nanocomposite and its photocatalytic activity in environmental remediation

摘要

ZrO2/Ag modified by polypyrrole was synthesized by chemical oxidative polymerization method. ZrO2 was prepared by hydrolysis of zirconyl chloride by maintaining pH 10. ZrO2/Ag was prepared by impregnation method. The sample were confirmed using various characterization techniques such as X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FT-IR), Diffuse Reflectance Ultraviolet-Visible Spectroscopy (DRS-UV-Vis), HR-SEM and UV-Visble spectroscopy. It is found that composite shows enhanced photocatalytic activity towards photodegradation of methylene blue (MB) dye under visible light.
