Abstract

In this work, zeolite NaY was prepared by hydrothermal method. Then, silver ions were replaced in the zeolite NaY with silver nitrate (AgNO3) solution via using ion exchange (IE) method. The Manganese dioxide (MnO2) nanoparticles (9.3 and 15.8 wt %) for guest were deposited in the zeolite AgY(host) structure with Mn(NO3)2 aqueous and KMnO4 solutions by confined space synthesis (CSS) method. Synthesized samples were studied and characterized via XRD, SEM/EDAX, FTIR, AAS and N2-BET techniques. The desulfurization  and  elimination  reaction of 2- chloroethyl phenyl sulfide (2-CEPS) and DEPPT (O, S-diethyl phenyl phosphonothioate) have been investigated by 15.8 wt% Nano MnO2/Zeolite AgY composite and MnO2  nanoparticles catalysts and via GC, GC-MS and 31 PNMR.
