Abstract

Photocatalytic removal of H2S was carried out on various TiO2-coated mesoporous ceramic filters with or without silver loading under UV light illumination. The photocatalyst surface and cross-section were investigated intensively with scanning electron microscopy and energy dispersive spectroscopy. The amount loaded, morphological and microstructural features of TiO2 coating were analyzed and the correlations to photocatalytic activity in removing H2S were discussed. The effect of silver loading on photocatalytic activity was also conducted. It was found that the silver-loaded TiO2 coating with sufficient thickness and abundant micro-cracks showed the best photocatalytic activity.
