Summary
-
1.
The reaction between nitrous oxide and cobalt-manganese spinels containing admixed lithium, titanium, and copper oxide has been studied.
-
2.
When the decomposition takes place on a spinel of nearly normal structure, the over-all kinetics are found to be first order, whereas zero order is observed on spinels of reverse or strongly distorted structure.
-
3.
N2O decomposition on spinels is retarded by oxygen present in the gas phase and also by oxygen sorbed by, or penetrated into, the spinel in the course of the reaction.
-
4.
It has been established that the activity of spinels varies symbatically with their capacity to chemisorb oxygen.
-
5.
Decomposition of chemisorbed N2O, or regeneration of active centers, will be the rate-determining step in the catalytic decomposition of nitrous oxide.
