Mechanistic approach for the kinetics of the decomposition of nitrous oxide over calcined hydrotalcites Original Research Article

A highly active catalyst for the decomposition of N2O was prepared by the thermal treatment of CoLaAl–hydrotalcite. For this catalyst the reaction rate was determined at various partial pressures of N2O, O2 and H2O in a temperature range from 573 K to 823 K. The kinetic simulation resulted in a mechanistic model. The energies of activation and rate coefficients are estimated for the main steps of the reaction.
