In this paper, Zeolite NaY was synthesized by sol-gel method in the absent the presence of organic templates and additives. Then, using ion-exchange method, it was transformed to zeolite AgY. In next step, a manganese dioxide nanoparticle was synthesized in the pores of zeolite AgY by confined space (CS) method. Nano-MnO2/Zeolite AgY composite was characterized by SEM, XRD, IR and AAS techniques. The decontamination reaction of 2-chloroethyl phenyl sulfide (mustard agent simulant) and dimethyl methylphosphonate has been investigated by nano-MnO2/Zeolite AgY composite. The results of GC analysis showed that 2-CEPS is produced about 86% by composite after 24 hours and it is changed to less toxic chemical products. The major of which, identified by GC-MS instrument, was phenyl vinyl sulfide (PVS). On the other hand, 31PNMR analysis showed absorption of DMMP of about 87% after 30 hours.
