Abstract

The decomposition of nitrous oxide over manganesedioxide was studied by the transient, response method proposed in our previous work. The analysis of response curves showed that the gaseous nitrous oxide decomposed directly on the active sites leaving oxygen on the surface. The amount of oxygen on the surface during the reaction at steady state was larger than the equilibrium amount, and it is suggested that the desorption of oxygen is one of the slower steps in the overall reaction. On the basis of the results obtained by the transient response method, a likely model for the decomposition wasproposed. The rate constants of all elementary steps were determined by the non-linear parameter optimization technique and it was found that the kinetic results were fully consistent with experimental findings.
