光催化剂可见光化研究进展

Progress on visible-lighted photocatalyst

光催化剂可将光能转变为化学能,可用于使水分解制氢及将环境中的有害物还原氧化为无害物质等,其应用前景十分广阔.而阻碍其应用的是不能有效地利用太阳光,因此研究开发可见光化的光催化剂就成为当前光催化剂研究中最重要的课题.本文简述了光催化剂的作用原理及较系统地介绍了可见光化光催化剂目前的研究现状及成果.

Photocatalyst has a spacious application prospect because it can be used to turn light energy into chemical energy,manufacture hydrogen by decomposing water and reduce or oxidize pollutant into innoxious substance.But it has not been applied far and wide for it is unable to utilize sunlight efficiently.Therefore,the research on the visiblelighted of photocatalyst has been one of the most important issues.The functional scheme,the present state and the research results in the filed of photocatalyst are introduced systematically in this paper.
