摘要：

The Ag/ZnO heterostructure microspheres were prepared via a simple one-pot triethanolamine (TEA)-assisted hydrothermal route and characterized by X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), X-ray Photoelectron Spectroscopy (XPS), UV-vis Diffuse Reflectance Absorption Spectra (DRS) and Photoluminescence Spectra (PL), demonstrating that Ag nanoparticles were attached on the surface of ZnO microspheres. The photocatalytic degradation of Rhodamine B (RhB) by the as-synthesized Ag/ZnO microspheres was investigated and optimized, indicating the best photocatalytic performance of Ag/ZnO of 1:150 (mol/mol). This may be attributed to the charge separation of photogenerated electrons and holes by Ag/ZnO heterostructure microspheres, which is interpreted by the proposed mechanism for Ag/ZnO heterostructure microspheres as catalyst.
