Abstract
This study draws a comparison between destruction potential of TiO<sub>2</sub> nano particles when its doped with Sulphur and Zirconium. When TiO<sub>2</sub> gets excited, it induces into electron pairs and holes and due to the presence of Sulfur in the nanoparticles, the energy of these pairs of electrons will be enhanced since S donates additional electrons during the reaction. While Zr has been found to improve the thermal stabilization of TiO<sub>2</sub> and it also increases its surface area. Fixed bed catalysis system was used to assess the destruction potential of H<sub>2</sub>S gas using S and Zr doped TiO<sub>2</sub> nanoparticles. The gas samples obtained were analysed using Gas Chromatography-Mass Spectroscopy to ascertain the percentage destruction of H<sub>2</sub>S gas before and after passing the gas samples from the doped TiO<sub>2</sub> nanoparticles. The results showed around 90% destruction of H<sub>2</sub>S gas using S-doped TiO<sub>2</sub> nanoparticles while doping with Zr proved to be very less effective for degradation of H<sub>2</sub>S gas as compared to S doped nanoparticles.
