摘要：

Pure and different content europium (Eu) doped mesoporous titania were prepared by template method using Eu(NO3)(3)center dot 6H(2)O and Ti(OC4H9)(4) as precursors and Pluronic P123 as template and characterized with X-ray diffraction (XRD), N-2 adsorption-desorption measurements, and ultraviolet-visible diffuse absorption spectra. Their photocatalytic activities were studied by photodegradation phenol in water under visible light irradiation. The results showed that Eu doping restrained the growth of grain size and extended the photoabsorption edge of mesoporous titania into the visible light region, which made Eu-doped mesoporous titania possess high photocatalytic activity under visible light. In the experiment condition, the photocatalytic activity of 0.2 mol.% Eu doped mesoporous titania was optimal of all the prepared samples.
