Description Co?Pt/ZSM-5 and Ag?Pt/ZSM-5 type catalysts
were prepared by ion exchange method followed by
calcination. These Co and Ag based catalysts, promoted by a small amount of Pt have been studied for their catalytic activity towards N2O decomposition. Both the catalysts show high catalytic activity, however, cobalt–platinum based catalyst shows relatively better activity at higher temperature. At 550 �C almost 100% conversion of N2O is achieved over Co?Pt/ZSM-5 with a maximum of
0.08479 mmole of N2O decomposed per gram of the catalyst
per unit time. These catalytic materials have been
characterized for their structure, composition, morphology
and other details, using XRD, SEM, EDX, ICP, BET techniques.
Much improved catalytic activity for the bimetallic
zeolite than the mono-metal containing compositions clearly
demonstrate the synergistic effect of these transition metals,
while high surface area of ZSM-5 is also responsible for the
improved N2O decomposition activity.
