Photocatalytic Performance of Ag Nanoparticles Modified ZnO Microplates Prepared by One-Step Method
Flower-shaped Ag-ZnO microplates were directly synthesized from an aqueous solution of zinc nitrate and silver
nitrate in the presence of CTAB at 120°C. The as-synthesized products were investigated in terms of their morphological,
structural, photocatalytic properties. Methylene blue (MB) and gaseous iso-propanol (IPA) are employed to evaluate
the photocatalytic activity of the Ag-doped ZnO microplates. The photocurrent response experiments are also carried out.
The as-formed composite shows higher efficiency of photocatalytic degradation on MB and IPA. Moreover, it also exhibits
obvious photocurrent under light irradiation.
Keywords: Ag nanoparticles, photocatalytic degradation, photocurrent, ZnO microplates.
