Mechanistic aspects of selective reduction of N 2 O by C 1 –C 3 alkanes resulting in N 2 , olefins, and hydrogen over CaO‐based catalysts were studied by combining catalytic tests at ambient pressure with transient analysis of products in high vacuum with microsecond time resolution. In the frame of this reaction, oxygen species formed from N 2 O participate in selective (olefin production) and nonselective (CO x formation) heterogeneous interactions. The coverage by these species and the interplay of exothermic heterogeneous (N 2 O decomposition and oxidative alkane conversions) and endothermic homogeneous (thermal nonoxidative dehydrogenation and cracking of hydrocarbons) reaction pathways determine the overall olefin selectivity.
