abstract: This paper reports the synthesis of Sm2InTaO7 and its photocatalytic activity on the degradation of crystal violet dye and reduction of Cr(VI) ions in aqueous solution. Sm2InTaO7 was prepared by sol-gel method at 1,200 C. For comparison purposes, Sm2InTaO 7 was prepared also by solid-state reaction at 1,400 C. The evolution of the crystalline phases of the sol-gel sample with the annealing temperature was followed by X-ray diffraction. The cubic crystalline structure of Sm 2InTaO7 was determined by Rietveld refinement method. Specific surface area was 5 m2g-1 for sol-gel sample and 1 m2g-1 for solid-state sample, whereas energy band gap was around 3.5 eV. Sm2InTaO7 prepared by sol-gel method showed better photocatalytic activity than Sm2InTaO7 prepared by solid-state reaction for the mineralization of crystal violet dye and reduction of Cr(VI) solution under UV-light irradiation. © 2012 Springer Science%2bBusiness Media B.V.
