In this work, a series of vanadia-loaded iron-oxide-pillared montmorillonite clays (V/Fe-PILCs) with various amounts of vanadia were prepared and studied for the selective catalytic oxidation of H2S. The prepared samples were characterized by X-ray diffraction (XRD), surface area-pore volume measurements, chemical analysis, X-ray photoelectron spectroscopy (XPS), and temperature-programmed desorption of ammonia (NH3-TPD). V/Fe-PILCs exhibited very good catalytic activity towards H2S oxidation at temperature ranging from 220-300 oC without any considerable SO2 emission. |
