“…The SSITKA technique is useful and powerful in capturing the kinetics and providing insights into the reaction mechanism [17]. Recent reviews of the SSITKA technique give a comprehensive overview of catalytic reactions that have been studied [17][18][19][20][21] and a few notable examples can be briefly mentioned. The Fischer-Tropsch mechanism for methane and C-C formation has been extensively studied using SSITKA modeling combined with DFT and kinetic isotope effect studies [22].…”

A prerequisite for the development or optimization of heterogenous catalysts is a comprehensive understanding of the reaction mechanism and kinetics at the level as elementary as possible. In comparison with steady‐state catalytic tests typically used for this purpose, non‐steady‐state (transient) studies provide deeper insights due to higher time resolution. For several decades, temporal analysis of products (TAP) and steady‐state isotopic transient kinetic analysis (SSITKA) have been successfully applied to the analysis of various heterogenous reactions. In this review, we highlight the contributions made by TAP and SSITKA studies between 2017 and 2023 to the understanding of reaction mechanisms and to the derivation of microkinetics. The versatility of these methods is illustrated by the examples of oxidative coupling of methane, CO/CO2 hydrogenation to hydrocarbons or methanol, metathesis of ethylene with 2‐butenes to propene, acrolein oxidation to acrylic acid, methanol conversion to olefins and non‐oxidative propane dehydrogenation to propene. We also provide our personal views on possible developments in this area.

CO hydrogenation is a promising approach for the storage of renewable energy in the form of hydrocarbons via the Fischer‐Tropsch synthesis (FTS). Since transient operation of FTS reactors might be necessary and even be beneficial, transient kinetics for a rational catalyst and reactor design are essential. In order to advance the development of such transient kinetics, the periodic transient kinetics (PTK) method was applied to the CO hydrogenation on a Co/TiO2 catalyst under FT‐like conditions. It was revealed that there are two carbon species of different reactivity, Cα and Cβ, present on the catalyst surface during the reaction. Cα forms fast within a few seconds and is highly reactive, while Cβ forms slowly, is accumulating on the surface over a longer time and imposes an inhibiting effect. The results indicate an important role of the Cβ species to chain growth and the formation of C2+ products. Finally, the transient experimental results are evaluated based on a material balance and the amounts of Cα and Cβ present on the catalyst surface during the reaction were determined.
