Abstract

This study demonstrates the synthesis of metal, semiconductor, and conductive polymer nanorods using anodized aluminum oxide (AAO) templates with uniformly open pores. The AAO templates were prepared via anodization with sulfuric, oxalic, and phosphoric acids, achieving pore sizes of approximately 25, 75, and 200 nm for precise nanomaterial synthesis. Electrochemical processes enabled the growth of metal [gold (Au), silver, nickel), semiconductor [cadmium selenide (CdSe)], and conductive polymer [polypyrrole (PPy), polyaniline] nanorods, as well as metal-polymer composites with varied morphologies. Characterization with scanning electron microscopy and energy-dispersive X-ray spectroscopy revealed growth mechanisms and changes influenced by pore size and material composition. Notably, during Au nanorod/PPy composite synthesis, PPy shrinkage and subsequent Au regrowth led to the formation of core–shell composites. These results demonstrate the potential of AAO templates for structural control and suggest applications in optoelectronics, electronic devices, and energy storage.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
