Fundamentals of HeterogeneousCatalysis: a Study of N2OMitigation ReactionOver Modified Zeolite Catalysts

This article provides the fundamental understanding of heterogeneous catalysis and the importanceof nitrous oxide (N2O) conversion reactions. Solid catalysts play an important role in the reductionof several greenhouse gases. In developing countries, the topic of N2O mitigation reactions isrelatively new and needsreview particularly for early stage researchers. In this work, reactioncatalysis, zeolite as a prominent catalyst support, and the importance of N2O dissociation reactionsare briefly discussed. After an overview of global warming, the discussions continue to introducethe principles of reaction catalysis. Furthermore, N2O is a potent greenhouse gas, whereas itsemissions into the environment can be reduced when reacted over active and selective solidcatalysts. Presently, Fe-ZSM-5 is commercially used catalyst for N2O conversion reactions.Zeolites, for example, H-ZSM-5 (HnAlnSi96-nO192.16H2O) are aluminosilicate catalyst support withunique physicochemical properties. Catalytic activity of H-ZSM-5 may vary when loaded withmetals or treated with acid/basesolutions. The selectivity of reaction product changes when thesame catalyst support is loaded with different metals.
