Kinetics of N2O decomposition over bulk and supported LaCoO3 perovskites

For the first time, kinetic data on the decomposition of N₂O over mixed oxide LaCoO₃ with a perovskite structure have been obtained. Bulk LaCoO₃ synthesized using microwave activation exhibited an increased intrinsic reaction rate with a 30 kJ mol^–1 lower activation energy. Perovskite samples supported on ZrO₂-La demonstrated lower intrinsic reaction rates due to the lower content of the LaCoO₃ phase, but the activation energies were also lower by 50–80 kJ mol^–1.
