The pure TiO2 and Cr doped TiO2 (TiO2:Cr) photocatalyst thin films were prepared by solgel method using chromium (III) chloride and tetra butyl orthotitanate with doping levels of 1 to 7 at. %. The structure of TiO2:Cr thin films was determined through XRD diffraction. Surface morphology and grain s...
