光催化反应中TiO_2负载改性的研究现状

Research Status of TiO_2 Load Modification in Photocatalytic Reaction

TiO_2是光催化反应中最常用的催化剂,在实际应用中具有一系列优点同时也具有很多缺陷,这些缺陷限制了其应用,所以必须要对TiO_2进行改性﹒本文简述了目前光催化反应TiO_2催化剂存在的问题,同时综述在光催化反应中玻璃类、金属类、陶瓷类、吸附剂类、高分子聚合物等载体材料对TiO_2的负载改性及负载型TiO_2固定方法的研究现状,并对下一步的研究方向作了进一步的展望﹒

TiO2 is the most commonly used in the photocatalytic reaction catalyst,which is of a series of advantages in practical application but also has many defects,these defects limits its application,so TiO2 must be modified.This paper briefly describes the current problems of TiO2 photocatalysis reaction catalyst,and application in photocatalytic reaction of glass,metal,ceramic,adsorbent,such as polymer carrier materials of TiO2 load modified type and the load the research status of TiO2 fixed method,in addition,the further research direction is prospected.
