摘要：

In the area of acid catalysis, adsorption microcalorimetry studies have allowed a significant insight in surface studies under certain experimental conditions. Consideration is given to the interpretation of the heat evolved when a basic probe molecule is adsorbed on the surface of crystalline or amorphous silica-aluminas. In particular, the number and strength of acid sites are discussed as functions of lattice structure, concentration and nature of framework cation and basicity of the probe molecules.
