or CO 3 − indicating the mineralization of DMCP to form CuCl 2 and CuCO 3 is shown. Even though more DMCP is reactively adsorbed on CuON, its decomposition is faster on CuONGO. Detected NO 2 , which is formed as an intermediate, causes the conversion of an unevaporated DMCP liquid to H 3 PO 4 , as supported by MS results. This mineralization of DMCP happens via an indirect contact with the catalyst. Thus, CuON and CuONGO are considered as highly powerful media for the decontamination of chlorophosphate-based nerve agents.

High surface area composites consisting of iron oxyhydroxides and graphite oxide/aminated graphite oxide are efficient media for adsorption/decontamination of a mustard gas surrogate (CEES).
