一种分散后修饰的纳米棒阵列电极的制备方法
摘要：
一种分散后修饰的纳米棒阵列电极的制备方法，本发明涉及一种纳米棒阵列电极的制备方法，具体涉及模板法生长的金属纳米棒经分散后修饰的纳米棒阵列电极的制备方法。它克服了现有技术使纳米线电极丰富的电极表面积并未得到充分利用的缺陷。本发明提供的技术方案是：溶解掉模板法生长的金属纳米棒的模板，使纳米棒可以自由操纵；应用分散剂和超声处理，将纳米棒在溶剂中充分分散，避免团聚，形成单根纳米棒的分散溶液；通过调控分散溶液中纳米棒的浓度，实现以可控间距的方式将纳米棒修饰到基底电极表面上。这样形成的金属纳米棒阵列电极，可以充分利用纳米棒丰富的表面积，只需组装极少量的纳米棒即可实现超高的扩散流量和法拉第电流，具有超高的电催化活性。
摘要（英）：

The present invention relates to nanometer rod array electrode, and is especially nanometer metal rod dispersing and modifying process of preparing nanometer rod array electrode with best utilization of surface area. The process includes the following steps: dissolving the template for growing nanometer metal rods, adding dispersant to the solvent and ultrasonically treating for well dispersing nanometer metal rods in the solvent, and regulating the concentration of nanometer metal rods to apply nanometer metal rods onto the surface of electrode base in controllable intervals. The nanometer metal rod array electrode has best utilization of the great surface area of the nanometer metal rods, very high diffusion flux and faraday current, and very high electrically catalytic activity.
