Final Report: Multifunctional Metal-Organic Frameworks for Efficient Degradation of Chemical Warfare Agents: Mechanism and Synthesis
Abstract
The overarching objective of this proposed project is to understand the reaction mechanisms of catalytic degradation of toxic chemicals by a type of solid-state porous materials (metal-organic frameworks, MOFs), and ultimately realize the precise and rational design of new multifunctional materials for the desired function. Two classes of toxic chemicals of interest are sulfur-based and organophosphate-based agents, which are commonly used as simulants in the research for the deactivation of chemical warfare agents (CWAs). The mechanism studies will involve the investigation of interactions between the toxic chemicals and the surface of solid MOFs, the reaction kinetics, diffusion, and reaction pathways. By using MOFs of varying topologies, metal nodes, pore sizes/shapes, and particle sizes, a structure-property relationship will be established for catalytic MOFs, which will guide the rational design and synthesis of multifunctional materials with better performance. As the structures of sulfur-based and organophosphate-based agents are very similar to that of sulfur mustard and nerve agents, this proposed study will offer important insight into new material discoveries for the rapid degradation of CWAs.
