SBA-15 modified with Cu or Fe was used for adsorption/oxidation of methyl mercapthane in the vapour phase. These solids were synthesized from SBA-15 using the template method with a non-ionic surfactant and impregnating the SBA-15 with Cu and Fe. The solids were characterized by using XRD, FTIR and isotherms of adsorption in N₂. An increase in the surface area, pore volume and mesoporosity of the SBA-15 with each metal was observed. Adsorption microcalorimetry is an effective method to measure thermal effects generated during the decomposition of methyl mercapthane.
