Nanomaterials in electrochemistry. Technical report number 19
Nanomaterials and electrochemistry have a long shared history, for example, the use of finely dispersed Pt particles as catalysts in fuel cell electrodes. This chapter, however, deals specifically with applications of template-synthesized nanomaterials in electrochemistry. The authors begin with an overview of template materials. Three possible electrochemical applications of such materials are then discussed. The first entails use of the template method for preparing ensembles of nanoscopic electrodes. The second application concerns the development of a new type of ion-permselective membrane -- the metal nanotubule membrane. These membranes can be viewed as universal ion exchangers as they can be electrochemically switched between cation permselective, anion permselective and non-permselective states. The transport properties of metal nanotubule membranes can also be made selective on the basis of either size or chemistry of the molecule to be transported; possible applications of these membranes in chemical separations are discussed. The final application reviewed here entails the use of the template method to prepare monodisperse nanoparticles of Li(+)-intercalation materials for possible use as electrodes in Li-ion batteries.
