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.
