Abstract:

The formations and transformations of the chemical bonds of reactants and intermediates on catalyst surfaces occur in conjunction with the evolution of heat during catalytic reactions. Measurement of this evolved heat is helpful in terms of understanding the nature of the interactions between the catalyst and the adsorbed species, and provides insights into the reactivity of the catalyst. Although various techniques have previously been applied to assessments of evolved heat, direct measurements using a Tian-Calvet microcalorimeter are currently the most reliable method for this purpose. In this review, we summarize the relationship between the adsorption/reaction energetics determined by microcalorimetry and the reactivities of supported catalysts, and examine the important role of microcalorimetry in understanding catalytic performance from the energetic point of view.
