摘要：

In this paper, Mn-doped flower-like ZnO microstructures with various doping concentration (0, 0.25, 0.5 and 1.0mol %) were fabricated using liquid phase deposition at room temperature. The phases and morphologies of Mn-doped flower-like ZnO microstructures were characterized by XRD, SEM and TEM. The photocatalytic performances of Mn-doped flower-like ZnO microstructures with various doping concentration were studied using methyl orange as the stimulant pollutant. The measured results indicated that Zn2+ maybe replaced by Mn2+ in the lattice of ZnO or exist on the surface of ZnO nanoplates as Mn3O4. Moreover, the experimental results prove that Mn-doped ZnO microstructures can improve the performance of photocatalytic degradation. The optimization of Mn content is 0.25mol%, and degradation rate for methyl orange can reach to 88.7%. ©, 2015, Journal of Functional Materials. All right reserved.
