利用AAO模板合成纳米材料

The Nanomaterials Synthesized by Using AAO Template

AAO模板具有高度有序的纳米孔阵列 ,其孔径在 5～ 2 0 0nm范围内可调控 ,已被用于制备金属、非金属、半导体、导电高分子等纳米粒子阵列、纳米电缆、纳米“三明治”结构、纳米管和纳米线等纳米材料。这些纳米材料在光、磁、电和催化等方面不仅具有重要的理论研究价值而且具有潜在的应用前景。本文综述了AAO模板纳米阵列孔的有序化、孔径的调控。

AAO template has a highly ordered nanoporous array with adjustable and controllable pore diameter ranged in 5 nm to 20 nm. It has been used to prepare nanoparticle arrays, nanosized cables, nanoscale 'sandwich' structures, nanotubes and nanowires of metals, nonmetals, semiconductors, conductive polymers and so on. These nanomaterials not only are of theoretical interest but also have potential technological applications in optics, electronics, magnetism and catalysis. In this paper the order of nanosized array pores, adjustment and control of pore diameter, assembling techniques, and the properties and applications of synthesized nanomaterials in AAO template are reviewed.
