Abstract Pure and carbon doped TiO2 thin films were grown by reactive pulsed dc magnetron sputtering of titaniumin argon, oxygen and carbondioxide atmosphere. Sputtering density, argon and oxygen flow rates were maintained at 5W/cm2, 10 sccm and 6sccm, respectively whereas the carbondioxide flow rate was varied. The thin films were investigated for their structural, optical, morphological and photocatalytic properties. Carbon doped TiO2 thin films show a near visible bandedge (390 nm) and higher photocatalytic efficiency; degradation rate of methylene blue is 0.799 μmol/l.d.
