【摘要】 本文制备了一系列ＴｉＯ２粉末催化剂，用光催化法降解室内空气中各种微量有机污染物，最终降解率接近１００％．考察了晶型对光催化剂性能的影响，结果表明，锐钛矿型ＴｉＯ２的催化性能最好．最后，分析了ＴｉＯ２光催化反应机理更多还原

【Abstract】 In this paper, a series of TiO 2 powder catalysts are prepared. The photocatalysis is proposeed to degrade indoors trace undesired organic contaminats acetone etc., the conversion approaches 100%. The effect of crystal form on photocatalysis property is studied. The results show that: Function of anatase TiO 2 is best. The probable mechanism of TiO 2 surface photocatalytic reaction is also suggested.更多还原
