| Abstract: | In this paper, a seriesof TiO2 pow der 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 TiO2 is best.The probable mechanism of TiO2 surface photocatalytic reaction is also suggested |
