Abstract

In this paper nanoparticles of lithium-cobalt oxide on alumina and silica substrates, by sol-gel method and with citric acid as gelling agent were prepared. The effects of different substrates on size, shape and catalytic effects of nanoparticles were studied. To evaluate the catalytic activity, rate of decomposition of hydrogen peroxide in the presence of any of the samples by measuring the volume of oxygen gas released at the time, was investigated. The X-ray diffraction patterns (XRD), scanning electron microscopy (SEM) and FT-IR spectra confirmed the formation of Co3O4 and LiCoO2 phases

Abstract

In this study, manganese dioxide nanoparticles were synthesized in the pores of zeolite 13X by supporting method and its morphology and structure were characterized by SEM, XRD, IR and AAS techniques. Decontamination reaction of 2-chloroethyl ethyl sulfide (a mustard agent simulant) was investigated by GC technique. The results of GC analysis showed that 2-CEES was completely absorbed by Nano-MnO2/Zeolite13X composite after 168 hours and converted to less toxic chemical product. Decontamination products formed via hydrolysis were hydroxyl ethyl ethyl sulfide and ethyl vinyl sulfide. Destruction reaction of DMMP nerve agent simulant via 31P NMR analysis showed that this composite after 36 hours demolished almost 32 percent of nerve agent simulant
