Novel Photocatalysts and Processes for the Destruction of Chemical Warfare Agents (CWA)
Abstract
This paper describes the initial work and research tasks undertaken for testing selected categories of photocatalysts for destruction of organics and CWA simulants, utilization of ultrasound for enhancement of reactant transformation and elimination of byproducts, and development of photocatalysts for operation with visible light. More specifically, we present the initial work we performed on the photodegradation of diethylsulfide (DES) in gas phase (C2H5-S-C2H5) as a simulant of mustard gas (HD) over various titanias utilizing UV light. The main routes of DES degradation are C-S cleavage, S oxidation, alpha-C and Beta-C oxidation were revealed. The liquid phase photodegradation of organics in the presence of ultrasound aiming at the enhancement of catalysts reactivity and elimination of any byproducts was studies as well. Effective photocatalysts for operation with visible light were synthesized based on transition metal substituted and loaded MCM-41. Extensive work is being performed involving the use of the above approaches for CWA simulants such as diethylsulfide, 2-chloro ethyl-ethyl-sulfide (ClCH22SCH2CH3) and dimethyl-methyl-phosphonate (DMMP).
