Abstract

Abstract:

Catalysts of cobalt-cerium composite oxide doped with series of alkaline earth metals were prepared using the citrate method. Results of catalytic activity tests showed that the addition of alkaline earth metals enhanced the efficiency of N2O decomposition according to the following order: Mg

Key words: N2O decomposition, Alkaline earth metal, Co3O4, CeO2, Composite oxide catalyst
