KINETIC AND THERMODYNAMIC STUDIES FOR THE H2S ADSOPRTION USING TiO2 NANOMATERIALS

This study is continuation of the studies carried out by our research group focusing on the catalytic and photocatalytic destruction of H2S gas using pure and doped TiO2 nanomaterials. To further study the H2S adsoprtion mechanism, kinectic and thermodynamic studies were carried out, folowed by adsorption isotherms like Langmuir and Freundlich isotherms. The reactions were assumed to be pseudo first order reactions. In agreement with our previous findings, lower activation energies were attained for 2% sulphur doped nanoparticles and nanofibers, the energy that of nanofibers being quite lower than the nanoparticles indicating the better destruction efficiency in case of nanofibers.
