摘　　要：纳米氧化锌(ZnO)作为一种半导体金属氧化物功能材料,它的诸多特性如荧光性、光催化活性、紫外激光发射、紫外线吸收、光电及压电性等被人们陆续发现并广泛应用于荧光体、高效催化剂、紫外线遮蔽材料、气体传感器、图像记录材料及压电材料等多个领域.ZnO由于其绿色、环保和高效等优点,近年来在环境污染控制方面受到人们的广泛关注.通过合成技术和条件控制纳米ZnO材料的粒径、表面态和形貌等参数可以提高光催化材料的光催化活性和量子产率.本文综述了本课题组对纳米ZnO材料的合成技术及其在光催化领域的应用研究,主要探讨了影响纳米ZnO材料光催化性能的相关参数.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.
