Abstract Pure and Ti3+ doped In2O3 nanostructures had been synthesized by facile hydrothermal method. The structural, morphological and optical properties were characterized by using XRD, FT-IR, HR-SEM and TEM, EDS, XPS, UV-DRS and PL techniques. X-ray diffraction analysis indicated that pure body-centered cubic crystal structure of In2O3. HR-SEM and TEM analysis showed nanoflakes and porous cube shaped nanostructure for pure and Ti3+ doped In2O3, respectively. XPS spectra revealed composition and elemental state of Ti, In and O. An optical band gap values decreased from 3.40 to 3.30 eV while doping. Violet, blue and green emission PL peaks were observed at room temperature. Photocatalytic activity for Methylene Blue (MB) dye degradation was improved by adding dopant Ti3+ into In2O3 host lattice. Reusability study of Ti3+ doped In2O3 was done to study about the stability of the catalyst.
