Anodic organic oxidations, general discussion

The widespread use of large-amplitude relaxation techniques in the investigations of anodic organic oxidations, requires further comment on the value of these methods. Reinmuth divided these techniques into three classes based on the types of applications quantitative kinetic studies, qualitative kinetic studies, and analytical studies. We are not concerned here with the analytical applications. For studies in kinetics, controlled-potential techniques, particularly linear-potential scan, in either single sweep or in cycles, and to some extent chronopotentiometry, have been primarily employed. Chronopotentiometry has been successfully utilized in the study of transient reactions, e.g., the reaction of CO with platinum oxide or the reaction of oxalic acid with platinum oxide, and the study of simple charge-transfer reactions with linear diffusion (cf. Refs. 159-161). However, since the general application of chronopotentiometry is severely limited for the study of anodic organic oxidations, as commented previously, this technique will not be further discussed. The quantitative analysis of data obtained by linear potential scan techniques is complicated because the form of theoretical results even for the simplest cases, requires the use of computers and consequently very little quantitative kinetic information has been obtained.

The choice of electrode materials in li-polymer batteries is generally similar to that in li-ion batteries with hquid electrolytes, except where the electrochemical stability of the polymer used is less stable to oxidation (by the cathode) or reduction (by the anode). There are several versions of organic polymer electrolytes discussed in this section. Some of the polymers are tme soHd polymers without substantial amounts of additives or plasticizers, and others are gels with a large volume of liquid electrolyte (up to 70% by volume). 

It is generally recognized [1 —16] now that chemisorbed carbonaceous species are formed during the anodic oxidation of many organic fuels. These species play an important role in our understanding of electrocatalysis. The techniques for their study, their properties and coverage of the surface under different conditions are discussed in this chapter. The role of adsorbed species in the oxidation of various fuels is dealt with in chapter X.
