“…This allows a good isothermal catalyst operation. TAP experiments have for these reasons been applied to study fast reactions over real catalyst samples [10][11][12][13][14] giving mechanistic information not easily accessible by other methods.…”

The mechanism of the HCN formation from ammonia and methane over Pt black was investigated using a temporal analysis of products (TAPs) reactor system. At 1173 K the hydrogen cyanide production rate depends on the order of introducing the reactants. HCN is formed rapidly on the methane pulse just after introducing ammonia. However, a slow formation of HCN is observed on the ammonia pulse that follows a methane pulse. Moreover the form of the HCN response resembles closely that of the nitrogen and hydrogen also released during the ammonia pulse. Thus, the rate-determining step for the formation of HCN is the decomposition rate of ammonia. A reaction sequence based on elementary steps is proposed for the HCN synthesis. The formation of HCN after pulsing H 2 points to a pool of surface intermediate species that are hydrogenated to HCN. #

“…In this way, information is obtained on the elementary steps of a reaction, since the time-resolved observations allow quantitative assessment of the accumulation of species on the surface [23,24]. In particular, transient studies have found widespread application in "three-way" catalysis, since these automotive catalysts inherently work under dynamic conditions [23][24][25][26][27][28][29].…”

“…We have already discussed the advantage of the high time resolution of TAP to provide industrially relevant information, by being able to distinguish between separate processes (section 3). There is a long history of direct industrial involvement in research with TAP, including, but not limited to, BASF, 187 Dupont, 136,[188][189][190][191] Haldor Topsøe, 192 Johnson Matthey, [193][194][195][196] Monsanto, 14,[197][198][199] Shell 18,188,200,201 and Toyota. 78,202,203 There is also evidence of topical TAP research which is relevant to industrial applications such as the Toyota Di-Air system, 204,205 reactions of methane, 206,207 NOx catalysis 110,203,208,209 and for better understanding of catalysts used in the production of industrial chemistry building blocks.…”

A detailed understanding of reaction mechanisms and kinetics is required in order to develop and optimize catalysts and catalytic processes. While steady-state investigations are known to give a global view of the catalytic system, transient studies are invaluable since they can provide more comprehensive insight into elementary steps. For almost forty years temporal analysis of products (TAP) has been successfully utilized for transient studies of gas phase heterogeneous reactions, and there have been a number of advances in instrumentation and numerical modeling methods in that time. Since TAP is a complex methodology it is often viewed as a niche specialty. With the purpose to make TAP more relevant and approachable to a wider segment of the catalytic research community, part of the intention of this work is to highlight the significant contributions TAP has made to elucidating mechanistic and kinetic aspects of complex, multistep heterogeneous reactions. With this in mind, an outlook is also disclosed for the technique in terms of what is needed to revitalize the field and make it more applicable to the recent advances in catalyst characterization (e.g. operando modes).
