Microcalorimetry Methods to Study the Acidity and Reactivity of Zeolites, Pillared Clays and Mesoporous Materials

摘要

Solid acids are among the most important categories of heterogeneous catalysis. Several techniques have been applied in order to determine their acidic properties, i.e.the number, strength and nature (Bronsted or Lewis type) of acid sites. A powerful method for this purpose is the measurement of the heats of adsorption of a base molecule using calorimetry (1,2,3,4).
