Electrode Materials State-of-the-Art and Experiments

To avoid any risk of galvanic corrosion, Tim Boretius et al. have introduced a new method of generating porous platinum surfaces by electrochemically depositing a platinum-copper alloy and a subsequent dissolution of copper [3] using cyclic

This chapter reviews in detail the principles and applications of heterogeneous electron transfer reaction analysis at tip and sample electrodes. The first section summarizes the basic principles and concepts. It is followed by sections dedicated to one class of sample material glassy carbon, metals and semiconductors, thin layers, ion-conducting polymers, and electrically conducting polymers. A separate section is devoted to practical applications, in essence the study of heterogeneous catalysis and in situ characterization of sensors. The final section deals with the experiments defining the state of the art in this field and the outlook for some future activities. Aspects of heterogeneous electron transfer reactions in more complex systems, such as...
