Decomposition of dimethyl methylphosphonate (DMMP) on alumina-supported iron oxide

Article Abstract:

The significance of phosphonate esters on the catalytic elimination of chemical warfare agents inspired scientific investigations on the subject. Experiments were performed to investigate the adsorption of dimethyl methylphosphonate (DMMP) on an alumina-supported iron oxide material. The findings demonstrate the adsorption of molecular DMMP on the alumina-supported iron oxide surface at room temperature, following the congestion of the surface sites and the passivation of the material.

The room temperature decomposition mechanism of dimethyl methylphosphonate (DMMP) on alumina-supported cerium oxide - participation of nano-sized cerium oxide domains

Article Abstract:

The adsorption and decomposition reactions of dimethyl methylphosphonate (DMMP) on cerium oxide supported on aluminum oxide are examined at 25 degree Celsius. It is proposed that dimethyl ether is formed by the reaction between two surface methoxy groups, while the reaction that yields methanol is driven by the interaction between DMMP and surface methoxy groups.

Decomposition of dimethyl methylphosphonate (DMMP) on supported cerium and iron co-impregnated oxides at room temperature

Article Abstract:

The experiments were done on the adsorption and decomposition reactions of dimethyl methylphosphate (DMMP) on cerium and iron oxides supported on aluminium oxide at 25 degrees C. The results suggest that the increased reactivity of these materials is due to the two-dimensional cerium oxide phase.
