Effect of CuO doped TiO2 on Morphology, Crystal Structure and Photocatalytic Activity

Abstract

Copper oxide doped Titanium Dioxide (CuO= 0-1.0wt.%) powders were prepared using sol-gel method and all the powder were sintered at 500 °C. The samples were characterized using X-ray diffraction(XRD), scanning electron microscopy(SEM), Brunauer-Emmett-Teller (BET) and UV/Vis spectrophotometer. The doping concentration of CuO gave significant influenced on the structural properties of TiO2. The lattice parameter, particles size and specific surface area of TiO2 size were increased with increasing CuO concentration. The degradation rate of methylene blue (MB) was calculated to investigate the photocatalytic activity of CuO doped TiO2. The degradation rate were increased when the concentrations of CuO increased.
