Preparation and characterization of Controlled Size of CdS Nanoparticles on the surface of TiO2 Nanoparticles and Nanotube by Colloid method

Synthesis of CdS nanoparticles using colloid method and then preparation of CdS/TiO2 nanocomposite and CdS/TiO2 nanotube and Samples prepared using SEM, UV-VIS absorption spectroscopy are investigated. These studies show that CdS nanoparticles are synthesized with relatively uniform dimensions and homogeneous structures. The SEM performed on samples showed CdS nanoparticles with 34 nm and TiO2 nanocomposites at 77 nm. The mechanism of photocatalytic activity on CdS /TiO2 nanocomposit and CdS /TiO2 nanotubes under visible light are also discussed.
