Nanofibers - A Simple and Practical Way Forward for Air Pollution Abatement

Abstract:

Nanofibers have proved to be highly efficient due to their enhanced adsorption capacity, because of high pores and very high surfacearea. Pure and Sulphur doped TiO₂ nanofibers were synthesized using electrospinning method in this study to evaluate their destruction potential for H₂S gas, using photocatalysis. Experiments were carried out under laboratory conditions using capillary glass tube reactor under UV light. 97% destruction was achieved using pure TiO₂ nanofibers while the destruction percentage decreased when S-doped TiO₂ nanofibers were replaced with the pure ones. Characterization of the nanofibers before and after running the experiments was carried out using XRD, SEM and EDX techniques. The destruction of H₂S gas was measured in ppm using BioGas Analyser fitted with GPA1.8 Gas pod for H₂S detection.
