Zinc oxide as a semiconductor metal oxide function material has been used as fluorophor,highly efficient catalyst,screening UV-ray agent,gas sensor,image recording material and piezoelectric material due to its many properties such as fluorescence,photocatalytic activity,ultraviolet lasing emission,ultraviolet absorption,photoelectric,piezoelectric properties,etc. Recently,ZnO nanomaterial has attracted much attention in the application of environmental pollution treatment due to its advantages of green,environmental protection and high efficiency. The photocatalytic activity and the quantum yield of the catalyst can be improved by some technical means of particle size,surface state,morphology,etc. In the paper,the synthesis and photocatalytic application of ZnO nanomaterials were summarized and some parameters which affected the photocatalytic property of ZnO nanomaterials were researched by our group.
