Abstract

Nanocomposites of nanoporous-TiO₂/In₂S₃ and np-TiO₂/Sb₂S₃ were formed by deposition of In₂S₃ or Sb₂S₃ using spray ion layer gas reaction technique from their precursor solutions onto nanoporous TiO ₂ substrates at temperatures of 150, 175 and 200 °C. The least penetration of the precursor into np-TiO₂ was achieved for np-TiO₂/In₂S₃ nanocomposites from indium acetylacetonate salt. The deepest penetration was obtained for both np-TiO ₂/In₂S₃(Cl) and np-TiO₂/Sb ₂S₃ nanocomposites with effective diffusion coefficients of 3.3 × 10^{- 3} cm²/s and 3.2 × 10 ^{- 3} cm²/s, respectively. The transport of the precursors in np-TiO₂ and the formation of different nanocomposites were described the regime of the Knudsen diffusion model.
