摘要：
For the first time, kinetic data on the decomposition of N2O 2 O over mixed oxide LaCoO3 3 with a perovskite structure have been obtained. Bulk LaCoO3 3 synthesized using microwave activation exhibited an increased intrinsic reaction rate with a 30 kJ mol-1 -1 lower activation energy. Perovskite samples supported on ZrO2-La 2-La demonstrated lower intrinsic reaction rates due to the lower content of the LaCoO3 3 phase, but the activation energies were also lower by 50-80 kJ mol-1. -1 .
