Iron Oxide on Magnesium Oxide Support as a New Destructive Adsorbent forChlorinated Hydrocarbons

摘要

In this study an overlayer structure of iron oxide on magnesium oxide support and pure magnesium oxide was synthesized in ultra fine particles of high surface area. The surface structure of Fe/MgO particles was studied by XPS, Mossbauer and XRD spectroscopy and surface chemisorption of CO2. The potential of both compounds to react with and decompose CCl4 was studied. Infrared (IR), powder X-Ray Diffraction (XRD) and Gas Chromatography (GC) measurements were applied to study the decomposition reaction with CCl4. The results of this study prove that magnesia-supported iron oxide (Fe/MgO) is about 15 times more efficient in reacting with and decomposing CCl4 than pure MgO.
