| 摘 要： | 采用一种简便的方法，合成了氧-硼共修饰的多壁碳纳米管材料，以此为载体制备的铂基催化剂具有更小的铂粒径、更高的电化学表面积(40 m2·gPt-1)和更高的氧还原活性(0.3 A·mgPt-1)。氧、硼在提高碳纳米管的载体分散性、控制铂颗粒的均匀性和粒径、促进氧还原反应的氧吸附/解离方面发挥着重要的作用。

| Abstract: | We synthesized an oxygen-boron co-decorated multi-walled carbon nanotube material by a simple method. After that, it was used as a carrier to prepare platinum-based catalysts and carried out a variety of characterizations. The results indicated that the platinum particles supported on this carrier showed smaller particle size, higher electrochemical surface area (40 m2·gPt-1), and higher oxygen reduction activity (0.3 A·mgPt-1). Predictably, boron and oxygen play an important role in improving the dispersion of carbon nanotubes, controlling the uniformity and size of platinum particles, and promoting oxygen adsorption/dissociation in the oxygen reduction reaction. |
