| Abstract: The template-synthesis method is a general approach for preparing nanomaterials. It involves the synthesis of the nanostructure of a desired material within the pores of a nanoporous membrane such as alumina and polycar-bonate membrane. Because the channels of these membranes are cylindrical with uniform diameter, monodisperse nanowires of the desired material are obtained. Depending on the chemistry of the pore wall and material, these nanowires may be either hollow (tubule) or solid (a fibril). This method has been used to prepare nanostructures composed of metals, carbons, semiconductors, polymers, and Li+-intercalation materials and some novel composite nanostructures. This article mainly reviews the general approach for the preparation of nanomaterials using a nanoporous alumina membrane as a template and its application. |
