Untersuchungen der Metall-Unterpotentialabscheidung und der Wasserstoffadsorption mittels elektrochemischer Mikrokalorimetrie

This thesis focuses on the study of heat effects upon electrode reactions with submonolayer conversions. These give information about the entropy change at the electrode/electrolyte interface. The employed calorimeter allowed the detection of temperature changes upon the conversion of a few nanomols per cm² electrode surface. Calorimetric studies were performed for various metal deposition processes from copper and silver containing electrolytes, and for hydrogen adsorption on platinum.
