Abstract: This review gives the characteristics of catalytic systems and results on the kinetics and mechanism of electrode chemical reactions, describes methods of determining the instability constants of complexes from the catalytic currents and the analytical use of catalytic boundary waves, and makes a comparison with results on corresponding non-electrode reactions of complex formation.
Among the bulk electrode chemical processes considered are theoretical and experimental results on an electrode reaction with two successive rate-determining chemical stages, and also on a double catalytic effect: that of the ligand and that of an addition of a polarographically active complex which is regenerated at the electrode.
The kinetics and mechanism of processes involving an adsorbed ligand-catalyst have been analysed on the basis of a concept of heterogeneous parallel reactions of complex formation.
