  • La-doped SrTiO3 catalysts with different La contents were prepared by a sol-gel method, and characterized by X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-Vis diffuse reflectance spectra (UV-Vis DRS), and low temperature nitrogen adsorption. The photocatalytic activities were evaluated by photo-degradation of methyl orange (MO). The results show that La-doped SrTiO3 keeps a perovskite structure and the absorption edge of 0.5% La-SrTiO3 sample is obviously red-shifted. There is no big difference between pure SrTiO3 and 0.5% La-SrTiO3 samples in particle size and morphologies. With the increase of La content, the photocatalytic activities of La-SrTiO3 samples under UV and visible light irradiation first increase, reaching a maximums around La content of 0.5%, and then decrease with further increasing La. Compared with pure SrTiO3, the 0.5% La-SrTiO3 sample obviously exhibits much higher UV and visible light photocatalytic activity. The enhanced photocatalytic activity can be mainly attributed to the increase of BET surface area, the enhancement in adsorption performance, the stronger absorption in 250~650 nm light region and the lower band-gap energy level.
