<p>A catalyst composition is provided effective for catalyzing the destruction of organophosphorus compounds including chemical warfare agents, pesticides, and solvents. The catalyst composition includes a catalyst material selected from the group consisting of vanadium oxide or manganese oxide or mixtures thereof deposited upon a catalyst support selected from the group consisting of alumina, silica or titania or mixtures thereof. Also, a method is provided for decomposing volatile organic compounds, including organophosphorus compounds including chemical warfare agents, pesticides, and solvents, by contacting the volatile organic compounds with a manganese oxide catalyst composition in the presence of visible light or with a catalyst composition heated to a temperature of at least 300 °C and most advantageously to at least 450 °C, thecatalyst composition containing a catalyst selected from the group consisting of manganese oxide, vanadium, vanadium oxide, activated carbon or diphosphorus pentaoxide. Spent catalyst composition may be regenerated for decomposing volatile organic compounds by washing the spent catalyst composition with distilled deionized water.</p> |
