Abstract:

TiO_x/CdS composites were synthesized by CdS deposition on TiO_x from aqueous solutions of Cd (CH₃COO)₂ and Na₂S with and without addition of a stabilizing agent–Na₂SiO₃. Initial high-defective TiOx nanocrystalline powders were prepared by pulsed laser ablation (Nd:YAG laser, 1064 nm, 7 ns) of Ti target in H₂O. Composites obtained exhibit absorption in the visible range up to 520 nm. On the example of Rhodamine C photodecomposition in water it was revealed that the nanocomposite TiOx/CdS powders obtained exhibit good photocatalytic properties when excited by visible light.
