文摘

ZnO/Mn hierarchical structures have been synthesized by a facile one-step solution route at room temperature and their structure, morphology, photoluminescence, and photocatalytic activity fully investigated. Reduced crystallite size and increased microstrain of ZnO were found on incorporation of Mn ions. Room-temperature photoluminescence spectra of the as-synthesized ZnO/Mn hierarchical structures presented violet and blue emission. Meanwhile, ZnO/Mn hierarchical structures exhibited enhanced photocatalytic activity compared with pristine ZnO. Optimal content (5%) of Mn ions in the ZnO matrix will lead to the highest photodegradation efficiency.
