Quantitative study of the decomposition of dimethyl methylphosphonate (DMMP) on metal oxides at room temperature and above

摘要: The adsorption and decomposition reactions of dimethyl methylphosphonate (DMMP) on a commercial γ-Al2O3, γ-Al2O3-supported iron oxide, sol−gel-prepared alumina have been examined at temperatures from 25 to 400 °C. capacities these solids for the DMMP measured, identities amounts products determined over entire temperature range. surfaces yield higher total than supported oxide material, with sol−gel showing very high activity. When corrected surface area, however, material shows an activity equal that γ-Al2O3 support. all up saturation surface, presumably because presence transitional phases more reactive sites. At °C, capacity 117 μmol/g, alumina-supported oxid...
