A simple and straightforward approach to prepare TiO2-coated carbon nanotubes (CNTs) is presented. Anatase TiO2 nanoparticles (NPs) with the average size ~8Â nm were coated on CNTs from peroxo titanic acid (PTA) precursor even at low temperature of 100Â Â°C. We demonstrate the effects of CNTs/TiO2Â molar ratio on the adsorption capability and photocatalytic efficiency under UVâvisible irradiation. The samples showed not only good optical absorption in visible range, but also great adsorption capacity for methyl orange (MO) dye molecules. These properties facilitated the great enhancement of photocatalytic activity of TiO2 NPs-coated CNTs photocatalysts. The TiO2 NPs-coated CNTs exhibited 2.45 times higher photocatalytic activity for MO degradation than that of pure TiO2.
