EMERGING MATERIALS FOR THE ELECTROCHEMICAL TREATMENT
OF POLLUTANTS
The preceding sections in this chapter have highlighted several instances
where new electrode materials and membranes have played a key role in the
electrochemical treatment of pollutants. In this section, we further elaborate
on this aspect and also consider recent developments in new electrolytes (e.g.,
molten salts, supercritical fluids). Materials science and engineering has much
to offer to its electrochemical counterpart in the common goal of pollution abatement.
Hence developments in each of these two disciplines will ideally have
to mesh with one another, "hand-in-glove", so that new solutions to pollution
problems can be found. This in turn entails effective communication between
the practitioners in each of the three disciplines and efficient cross-fertilization
of ideas. In this regard, it is significant that the number of environment-related
papers and symposium topics in electrochemistry and materials-related journals
and conferences is on the upswing. This trend is likely to continue. Individual
classes of materials are considered next.
