Impregnated (iron oxide and cerium oxide) and non-impregnated aluminas were compared and characterized to find the best catalyst for destruction of organophosphorus compounds at room temperature. DMMP was used for the purpose of this study. A micro reactor with detection of products by Fourier transform infrared spectroscopy was used to study the formation of products as a function of composition. Although dissociative adsorption of DMMP on non-impregnated alumina occurs at room temperature, it was observed that the impregnated (iron oxide and cerium oxide) alumina is more active towards dissociative adsorption of DMMP than the non-impregnated alumina. The impregnated (5 wt% Fe and 7.5 wt% Ce) Versal GH alumina has the highest accumulated product formation so far investigated. When the sample was exposed to atmosphere overnight the accumulated product formation was lowered because of the adsorption of water. However, when the sample was pretreated at elevated temperature, there is a complete recovery of the activity.
