Photocatalytic Activity of B-TiO2 Prepared Using Boric Acid as Boron Source
Boron doped TiO2 photocatalysts was prepared by sol-gel method. The influences of Boric acid amount, reaction time and calcination temperature on photocatalytic activity of the prepared B-TiO2 were studied. The boron doped TiO2 had small adsorption capacity. 38.8% of the initial methyl orange was degraded on the sample prepared with 1% B2O3 after 30 min of irradiation. After 120 min of irradiation, nearly 100% of the methyl orange was degraded on the material. Photocatalytic activities of the boron doped TiO2 materials increased from 400 oC up to 500 oC. After that, degradation activity decrease with further increase of calcination temperature in the range from 500 oC to 600 oC.
