Electrodes with a defined mesoscopic structure

The possibility of characterizing the real-space morphology of electrode surfaces on the nanometer scale using scanning probe microscopy (SPM) gives access to the influence of mesoscopic structures on electrochemical processes. Various possibilities of creating defmed mesoscopic structural properties of electrode surfaces are discussed. Special emphasis is put on structure and behavior of supported metal clusters, which can be regarded as model systems for electrocatalysts used in technological processes.
