用电化学方法制备了聚苯胺(PANI)和铂颗粒的层层结构复合材料。层数和外层(聚苯胺或铂)的性质决定了复合材料对甲醇氧化的电催化性能。我们证明了逐层形成纳米复合材料的方法，并用一层PANI对铂颗粒进行修饰，可以显著提高催化效率。
A new composite material based on the electrochemical generation of a layer-by-layer structure of polyaniline (PANI) and Pt particles has been prepared. The number of layers and the nature of the external layer (PANI or Pt) determine the electrocatalytic performance of the composite for the oxidation of methanol. We demonstrate that the layer-by-layer approach to form the nanocomposite and modification of the Pt particles with a layer of PANI leads to substantially higher catalytic efficiency.
