✦ Synopsis

In the field of heterogeneous catalysis, variations in temperature, pressure, or reactant concentration are commonly encountered under real operating conditions. Experiments to identify transients, such as the titration of adsorbed species, exchange of isotopically labeled reactants, and step changes in the reaction conditions are invaluable tools in understanding the synergy between the catalyst nanostructure and the kinetics of a catalytic reaction. [1] When deciding between competing kinetic models, often the key distinguishing feature is their ability to model transient as well as steadystate behavior. Furthermore, the analysis of oscillations in kinetics and spatio-temporal pattern formation on catalysts can greatly increase our understanding of dynamic processes and interactions on catalyst particles.
