Microcalorimetric study of the catalytic properties of SBA-15 modified with Cu or Fe for adsorption/oxidation of methyl

Abstract

SBA-15 modified with Cu or Fe was used for adsorption/oxidation of methyl 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.
