Synthetized of Ag-doped TiO2 nanostructures by silver mirror reaction and their photocatalytic activity

Abstract

The nanocomposite materials such as Ag/ TiO2 nanobelts and Ag/ TiO2 nanoflowers are synthesized and their photocatalytic properties are studied. With the simple hydrothermal synthesis, TiO2 nanobelts and nanoflowers are fabricated from commercial nanoparticles, followed by deposition of Ag nanoparticles through the silver mirror reaction process. According to the photocatalytic measurments, Ag/ TiO2 composite nanostructures are proved to have a better photocatalytic activity than that of nanostructures without silver doping, i.e. TiO2 nanobelt, and nanoflower structures.
