  Abstract

A series of V2O5-TiO2 xerogel catalysts were prepared by nonhydrolytic sol-gel method and analysed by various characterization techniques. These catalysts showed much higher surface areas and total pore volumes than conventional V2O5-TiO2 xerogel and impregnated V2O5/TiO2 catalysts. It was found that the textural property of V2O5-TiO2 material varies with the method and conditions of synthesis. Surface vanadates and TiO2 anatase phase are the crucial factors to obtain high catalytic activities. The selective oxidation of hydrogen sulfide in the presence of excess water and ammonia was studied over these catalysts. Xerogel catalysts prepared by non-hydrolytic sol-gel method showed very high conversion of H2S without harmful emission of SO2. The highest catalytic activity shown by these V2O5-TiO2 catalysts may be due to their high surface area and good dispersion of vanadia species in the titania matrix.
