摘要：

Nano silver particles loaded on micrometer-size TiO2, nanosize TiO2, and BiVO4 were prepared by a silver mirror reaction (SMR), which is an old and well-known method. Morphology of silver on the surface of semiconductor particles was characterized by energy dispersion spectrum, transmission electron microscopy, and electron backscatter diffraction. The photocatalytic activities of these photocatalysts were evaluated by the degradation of methyl orange and hydrogen production under UV and visible light irradiation, respectively. The experimental results indicated that the photocatalytic activities of Ag/TiO2 and Ag/BiVO4 composites prepared by the SMR were remarkably higher than those prepared by the photoinduced deposition method.
