Over the course of this grant, three main projects were conducted in to gain a better understanding of the decomposition of sulfur and phosphorus-based chemical warfare agents. The first project involved studies of the thermally-activated decomposition of dimethyl methylphosphonate (DMMP) on bimetallic Au-Pt clusters; one of the main problems with transition metal catalysts is that phosphorus is difficult to remove from the surface and poisons that catalyst for further reaction. ...
