英文摘要	Highly dispersed tio2/sba-15 photocatalysts were successfully synthesized by solvothermal treatment using titanium n-butoxide (tb) and carboxylate. modified sba-15 (cooh/sba-15) as raw materials. the good dispersive carboxyl groups of cooh/sba-15 coordinated with tb molecules to anchor them. after solvothermal treatment, the tb molecules were transformed into tio2 nanoparticles and finally formed the tio2/sba-15 products. the products were calcined to improve the crystallization of tio2 and to remove the organic compounds. as. obtained tio2/sba-15 photocatalysts were characterized by x. ray diffraction (xrd), nitrogen adsorption, fourier transform infrared (fi-ir) spectroscopy, and transmission electron microscopy (tem). analytical results showed that the as. obtained tio2/sba-15 photocatalysts possessed a better mesoporous structure and a larger specific surface area. the highly crystalline anatase tio2 nanocrystals dispersed well on the surface of sba-15. rhodamine b (rhb), as a photodegradation target, was used to evaluate photocatalytic performance under uv light irradiation. the as. obtained tio2/sba-15 photocatalysts exhibited much better photocatalytic activity compared with the photocatalysts prepared by a post. synthesis impregnation method.
