Similar approach has also been taken by Ferain and Legras [133,137,138] and De Pra et al. [139] to produce nanostructured materials based on the template of the membrane with etched pores. Polycarbonate film was also of use as the base membrane of the template, and micro- and nanopores were formed by precise control of the etching procedure. Their most resent report showed the successful formation of ultrasmall pores and electrodeposited materials of which sizes were as much as 20 nm [139]. Another attractive point of these studies is the deposited materials in the etched pores. Electrochemical polymerization of conjugated polymer materials was demonstrated in these studies, and the nanowires based on polypyrrole or polyaniline were formed with a fairly cylindrical shape reflecting the side wall structure of the etched pores. Figure 10 indicates the shape of the polypyrrole microwires with their dimension changes by the limitation of the thickness of the template.

Zhou et al. reported template-synthesized cobalt porphyrin/polypyrrole (TPPS-Co/PPy) nanocomposite and its electrocatalysis of oxygen reduction in a phosphate buffer solution (PBS) [97]. With the assistance of ultrasonication and different preparation procedures, the nanocomposite can be electrochemicaUy synthesized with uniform 2-D and 3-D nanostructures.
