Abstract :

A comparative study of the H2S gas destruction efficiencies of TiO2 nanoparticles and nanofibers has been carried out. 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. Nanoparticles have been synthesized using co-precipitation method while electospinning technique was used to prepare the nanofibers. Regression modeling has been performed to ascertain the individual degradation rates of the nanoparticles and nanofibers. Oxidation rates which give a relationship between gram moles of H2S converted per minute per gram of catalyst have also been used to compare the destruction efficiencies of both the nanoparticles and nanofibers.
