Anatase TiO{sub 2}/CNT composites of different CNT ratio were prepared by solvothermal method. The X-ray diffraction analysis result showed that the sample has characteristic peaks of anatase TiO{sub 2}. CNT incorporated TiO{sub 2} showed less peak intensity when compared to bare TiO{sub 2}. The grain size was calculated using the Scherrer equation and it is found to be ∼ 2.38 and 2.46 nm for pure TiO{sub 2} and 5% CNT/TiO{sub 2} composites respectively. Optical properties were studied using UV-visible diffuse reflectance analysis and photo luminescence analysis respectively. UV analysis reveals the shift in absorption peaks towards the visible region for composites when compared to bare TiO{sub 2} powder. Raman spectroscopy studies show the presence of characteristic peaks corresponding to anatase TiO{sub 2}, CNT. Morphological nature of the compounds was studied using High Resolution Transmission Electron Microscopy analysis respectively.
