在这篇文章中，我们提出了第一次通过使用电加热管式反应器生产由碳纳米管支撑的高活性Pt催化剂的连续方法。合成的催化剂具有高度的分散性和窄的簇尺寸分布。与通过常规油浴法合成的催化剂相比，达到了显著更高的电催化活性，这可以归因于更高的金属负载量和更小且更均匀分布在碳载体上的Pt颗粒。我们的方法介绍了一种简单，省时和成本效益的方法，燃料电池催化剂的制备在流动反应器，可在大规模使用。
In this contribution we present for the first time a continuous process for the production of highly active Pt catalysts supported by carbon nanotubes by use of an electrically heated tubular reactor. The synthesized catalysts show a high degree of dispersion and narrow distributions of cluster sizes. In comparison to catalysts synthesized by the conventional oil-bath method a significantly higher electrocatalytic activity was reached, which can be attributed to the higher metal loading and smaller and more uniformly distributed Pt particles on the carbon support. Our approach introduces a simple, time-saving and cost-efficient method for fuel cell catalyst preparation in a flow reactor which could be used at a large scale.
