Preparation and Characterization of La-B co-doped TiO2 Photocatalyst

La-B-TiO2 photocatalysts were prepared using tetrabutyl titanate, tributyl borate, and lanthanum chloride as the precursors by solvothermal method. The prepared sample is composed of irregular particles with fairly rough surface in the size Within 5 mu m. Large surface area and pore volume are benefit to adsorption and photocatalytic degradation activity of the materials. Pore size of the 1%La-3%B-TiO2 sample mainly distributes in the range between 5-35 nm. Specific surface area of the material is 101.45 m(2)/g. The sample containing 0.5% La presents the maximum decoloration efficiency. When La content is 0.5%, methyl orange adsorption rate on the material is less than 5%, and photocatalytic degradation rate is 39.9%.
