A process of TiO 2 photosensitization by coupling it with a narrow band gap semiconductor has been investigated here. Distinct TiO 2 /Ag 2 S nanocomposites were prepared by a single-source decomposition method. After sensitization, the TiO 2 material

The synthesis of distinct nanocrystalline TiO2 capped ZnS samples was carried out using a chemical deposition method. The materials characterization showed that the presence of ZnS onto TiO2 surface results in a red shift of the material band edge wh
