摘要：
The Mn-doped ZrO2/TiO2 nanostructured photocatalysts had been prepared by the simple hydrothermal method. The morphologies and structures of the as-prepared photo-catalyst were characterized by transmission electron microscopy, x-ray diffraction, x-ray photoelectron spectroscopy, and electron paramagnetic resonance. The resultant nanostructured photocatalysts exhibited high photocatalytic activity under ultraviolet (UV) light irradiation, attributing to the improvement of the photo-absorption property and the separation efficiency of photo-generated electrons and holes. The hydroxyl radicals (center dot OH), superoxide radical (center dot O-2(-)), and holes (h(+)) are the main active species in aqueous solution under UV light irradiation.
