The heterojunction structures of In2O3/TiO2, exhibiting visible light photocatalytic efficiency, has been synthesized by utilizing maleic acid as an organic linker to combine In2O3 and Degussa P25 (TiO2) nanoparticles. The prepared nanocomposite has been characterized by FESEM, TEM, XRD and UV-Visible reflectance spectra. The photocatalytic efficiency of the composite photocatalyst has been investigated based on the decomposition of 2-propanol (IP) in gas phase and 1,4-dichlorobenzene (DCB) in aqueous phase under visible light (lambda >= 420 nm). The extraordinary high photocatalytic efficiency of this composite In2O3/TiO2 under visible light has been explained on the basis of relative energy band positions of the component semiconductors.
