Abstract:
Using SBA15 as carrier and tetrabutyl titanate as titanium source, the SBA15 molecular sieve loaded with TiO2 was prepared by solgel method. The different mass concentrations of lanthanum nitrate were loaded onto TiO2-SBA-15 by impregnation method, and TiO2-SDA-15 catalysts with different lanthanum loading were prepared by high temperature calcination method. The series of catalysts were characterized by X-ray diffraction (XRD), infrared spectrum (FTIR), inductively coupled plasma (ICP) emission spectrum, transmission electron microscopy (TEM) and N2 adsorptiondesorption isotherm. The TiO2-SBA-15 catalysts with different La mass contents were used as photocatalysts to degrade the solution of methyl orange. We investigated the effect of La loading mass content on the degradation rate of methyl orange. The experimental results show that the degradation rate of methyl orange is 100% when La loading mass content is 0.14% and UV lamp irradiation for 140 min.
Key words: La loading, molecular sieve, titanium dioxide, photocatalysis, methyl orange
