Abstract

Abstract: Iron doping TiO₂/bentonite composite photocatalyst were prepared by sol-gel method. XRD and IR analysis were used to detect these samples. The photocatalytic properties of these samples were detected by decoloration rate of methyl orange solution and COD. It indicated that the photocatalytic properties of this kind of photocatalyst were prominent. The decoloration rate of 20 mg/L methyl orange solution at pH=4 under visible light could reach to 95% with COD more than 85%.Moreover,this catalyst could be reused several times after sintering at 200℃ for 2.5 h.

Key words: composite photocatalyst, bentonite, decoloration rate, COD
