The microcalorimetric technique has been applied to investigate the strongest active sites of zeolites, heteropolyacids and perovskites. The differential heats of adsorption of carbon monoxide, ammonia and oxygen were determined. The results imply that the method is very useful in the identification and characterization of the most reactive active sites of solid catalytic materials.
