The band gap energy of Zn and Cr doped TiO obtained by UV-DRS was 2.7 and 2.3 eV, respectively. The photocatalytic activity of catalyst was tested by photocatalytic degradation of phenol. Results show doped TiO is more efficient than pure TiO at photocatalytic degradation of phenol. Ti0.9Cr0.1showed enhanced activity. This enhanced activity was attributed to smaller crystallite size (12.6 nm), synergistic effect between anatase and rutile phases and larger specific surface area (160.11m/g).
