doi:10.7517/j.issn.1674-0475.2002.03.185

Abstract

Abstract: The effect of doping transition metal ions for the nano paticle TiO₂ on photocatalysis property was studied.The results indicate that the modifications of the second period transition metal ions to TiO₂ films are more effective than that of the first transition metal ions.The modification of ⅡB?ⅥB metal ions to TiO₂ films are better.The surface of the catalyst is characterized by XRD,SEM,XPS,and DTA.The results show that TiO₂ crystal is anatase and the radius of the crystalline grains is 32.58 nm.

Key words: TiO₂, photocatalysis, doping ion
