In this study, the activity test and characterization were performed to evaluate the hydrogen sulfide removal characteristics using a V/TiO2 catalyst at room temperature. The optimal vanadium loading was 1 0 w t % , a n d t h e d u r a b i l i t y w a s g r e a t e r t h a n 60 minutes at 60~80% relative humidity. The Brunauer-Emmett-Teller (BET) surface area and raman spectroscopy results con-firmed that the structure of the vanadium site exposed to the surface was a dominant factor in catalyst activity. From Scanning Electron Microscope (SEM), Energy Dispersive Spectroscopy (EDS) and X-ray crystallography (XRD) analyses, it was found that sulfur can be accumulated on the catalyst surface, which results in a decrease in durability under catalytic activity tests. Therefore, it is judged that a combined process of catalytic oxidation and regeneration is needed.
