Comparison of H2S gas destruction potential using TIO2 nanofibers and nanoparticles.

TiO2 nanoparticles and nanofibers have been used to carry out a comparative study of the destruction of H2S gas. Effects of sulphur doping have also been incorporated to assess the maximum destruction potential of the nanomaterials. An analysis has been made in this paper to evaluate and compare the performance of pure and sulphur-doped TiO2 nanoparticles and nanofibers for the destruction of H2S gas using photocatalysis under laboratory conditions. Regression modelling has been performed to ascertain the individual degradation rates of the nanoparticles and nanofibers. In addition, oxidation rates of H2S gas using the nanoparticles and nanofibers have been used to further elucidate our findings. It was observed that the destruction potential of nanofibers was 10 times more as compared to nanoparticles.
