Description Ru + Ag/US-Y and Ru + Co/US-Y based catalysts have been studied for their catalytic activity towards
N2O decomposition, a reaction of current environmental importance. Ruthenium-cobalt based catalyst
shows higher catalytic activity than the ruthenium-silver-based catalyst. Almost 90% conversion ofN2O
is achieved over Ru + Co/US-Y at 583 Kwith amaximumof 0.134 mmol of N2O decomposed per gramof
the catalyst per unit time. These catalytic materials have been characterized for their structure,
composition, morphology etc. using XRD, SEM, EDX, ICP, BET techniques. The synergistic effect of
transition metals as well as chemical properties of US-Y are responsible for the excellent catalytic
activity for N2O decomposition reaction. The redox capacity of Co may also be responsible for the
relatively better activity of Ru + Co based catalyst as compared to that of Ru + Ag based catalyst. These
catalysts are thermally stable and can be used for the direct decomposition ofN2Oemissions even under
high concentration.
