Comparitive Study of Differently Prepared V2O5-TiO2 Catalysts for the Selective Oxidation of H2S |
| 초록 |
Vanadia-titania catalyst prepared by different methods such as impregnation, supercritical sol-gel method, and non-hydrolytic sol-gel method are investigated for the selective oxidation of hydrogen sulphide to elemental sulfur and ATS. 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 surface area and pore volume exhibited by vanadia-titania catalyst are appreciable. The highest catalytic activity shown by V2O5-TiO2 catalyst prepared by non-hydrolytic sol-gel method may be due to their high surface area and good dispersion of vanadia species in the titania matrix. |
