英文摘要：
Nano ZnO has been used as a promising photocatalyst in degradation of many toxic organics in many studies.In this paper the basic physical and chemical properties and mechanism of photocatalytic process were described briefly.Preparation methods of ZnO were compared,and liquid phase processes were emphasized.As a photocatalyst,ZnO has some drawbacks,such as its poor response to visible light,quick recombination of charge carriers and critical drawbacks of photocorrison.Researches about surface metallization,doping,conjugation of metal oxides and surported ZnO catalyst to overcome these minors were reviewed.And finally,the development prospect and problems in photocatalytic technology of ZnO to be solved were presented.
