ABSTRACT
ABSTRACT The electrochemical properties of conductive transition metal oxides for electrocatalysis are illustrated and discussed. After a description of the preparation procedure and the resulting morphology, the structure of the oxide-solution interface is discussed in terms of surface acid-base properties and point of zero charge-structure correlation. The use of voltammetry as an in situ electrochemical spectroscopy is illustrated with specific examples. Electrode reactions such as oxygen, chlorine and hydrogen evolution, oxygen reduction, and organic oxidation are discussed in terms of mechanism and electrocatalysis. A generalized gas evolution reaction mechanism is put forward. Stability problems are finally scrutinized.
