Scanning Electrochemical Potential Microscopy (SECPM) and Electrochemical STM (EC-STM)


Scanning electrochemical potential microscopy (SECPM) and electrochemical scanning tunnelling microscopy (EC-STM) allow for imaging the solid-liquid interface under in situ electrochemical conditions. In this chapter we take a look at two important aspects of SECPM and EC-STM studies: First, investigations on model electrode systems relevant for electrocatalysis are presented. Second, studies on the behavior of biomolecules immobilized on electrodes are shown. In both cases the use of EC-STM or SECPM allows for insights into the electrochemistry at a molecular level which cannot be achieved by other, rather integrating, methods.
