The photocatalysts of Fe3+ or La3+ doped TiO2/natural zeolite and Fe3+ and La3+ co-doped TiO2/natural zeolite were prepared with Ti(OBu)2 as an initial material, anhydrous ethanol as a solvent, natural zeolite as a carrier and glacial acetic acid as a depressor by a sol–gels method. The experiments of photocatalytic oxidation of methyl orange were carried out in a self-made reactor with the light resource from a ultraviolet radiation antiseptic lamp. The effects of crystal structure and surface character on the photocatalytic activity of the photocatalyst samples were analyzed by X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy, respectively. The results indicate that the photocatalytic activity of La3+ and Fe3+ co-doped TiO2/natural zeolite is better than that of Fe3+ or La3+ doped TiO2/natural zeolite, and the photocatalytic activity of La3+ doped TiO2/natural zeolite is better than that of Fe3+ doped TiO2/natural zeolite.
