摘要：
MCM-41 and MCM-41 modified with cesium were synthesised and utilised as supports of iron species, to be used as catalysts in the Fischer-Tropsch reaction. X-Ray Diffraction (XRD), Specific Surface Area (BET), Mossbauer Spectroscopy (MS) in controlled atmosphere, between room temperature (RT) and 15 K, CO chemisorption and Volumetric. Oxidation (VO) were used to characterise the solids. The cesium presence produces lower iron reducibility and a unique fraction of very small metallic iron crystals. These structural properties lead to a high turnover frequency and an increase of the selectivity towards light olefins.
