TiO2/La2Zr2O7 composites were fabricated by sol-gel method. The composites were characterized by X-ray powder diffraction (XRD), Raman spectrum, scanning electron microscopy (SEM), energy dispersive X-ray spectrometer (EDS) and Brunauer-Emmett-Teller (BET) nitrogen adsorption. The results showed that TiO2 was uniformly coated on the surface of La2Zr2O7 powders. The BET surface area of TiO2/La2Zr2O7 composites was 26.78 m2/g, which was larger than that of La2Zr2O7. Also, the photodegradation of methyl orange was used to evaluate its photocatalytic property. It was found that TiO2/La2Zr2O7 composites showed good photocatalytic activity and the decomposition of methyl orange had basically completed within 30 min.
