Thermal stability and repartition of potassium promoter between the support and active phase in the K-Co2.6Zn0.4O4|α-Al2O3 catalyst for N2O decomposition: Crucial role of activation temperature on catalytic performance
Crucial role of activation temperature on K/Zn0.4Co2.6O4|Al2O3 deN2O performance. K migration from the support to the spinel nanocrystals upon temperature increase. KxCoO2 overlayer formation deteriorates catalyst activity.
