A final report on the study of ultrafine metal oxide particles as destructive adsorbents for toxic substances is presented. Successful treatment of organophosphorous compounds and chlorocarbons, where heteroatoms are extracted forming nontoxic metal phosphates and chlorides, has been carried out. Methods for preparing the nanoscale particles, including coreshell overlayer particles, have been worked out. Surface characterization, surface chemistry, heats of adsorption, surface catalyzed CHD2 yields CDH exchange, effect of surface --OH groups, electron transfer processes, 160180 exchange, and studies of molecular metal oxides have been reported. A patentable invention dealing with Fe2O3MgO coreshel structures is also described. Overall, 11 graduate students, research associates, and visiting professors have been involved in this work.
