“Raman Spectroscopy of Metal-Organic Frameworks For Chemical Warfare Agent Degradation”

Metal-organic frameworks are porous materials that can be used as catalysts for the decontamination of chemical warfare agents. The characterization of metal-organic frameworks and interaction between chemical warfare agent and framework is usually studied via x-ray diffraction, nuclear magnetic resonance, infrared spectroscopy and isotherm measurements to study reactivity and to monitor efficacy of uptake of guest molecules. I propose to develop and use Raman spectroscopy as a powerful tool in the study of defective metal-organic frameworks. I will use Raman spectroscopy to disentangle the complex interplay between framework topology, geometry, particle size, and defect density as they influence the uptake and bonding of chemical warfare agent simulants to the frameworks as well as how the simulant molecule alters the local environment of the framework. In turn, this information coupled with the standard measurements will aid in the determination of a set of design rules for creating highly catalytically-active metal-organic frameworks for chemical warfare agent degradation.
