In this work, polydopamine (PDA)-coated multi-walled carbon nanotubes (CNTs) have been employed as reactive platforms for the anchoring of multiple heteroatom dopants. Single-, double-, and triple-doped CNTs with the elements N, S and B have been successfully prepared and systematically investigated as electrocatalysts for the oxygen reduction reaction (ORR). The obtained catalysts have been fully characterized by the nitrogen-adsorption technique, transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy. Combining with the physicochemical properties of different doped CNTs and their catalytic performance, various doping modes are compared and the mechanism of these processes has been investigated. The synergetic effects on double and triple doped CNTs with N, S, and B are found. The new non-metal catalyst N–S–B-CNTs exhibits high electrocatalytic activity and good stability for ORR.

用N，S和B掺杂碳纳米管以进行电催化氧还原：单，双和三掺杂模式的系统研究

在这项工作中，聚多巴胺（PDA）涂层的多壁碳纳米管（CNT）已被用作锚固多种杂原子掺杂剂的反应平台。已经成功制备了具有元素N，S和B的单，双和三掺杂CNT，并系统地研究了它们作为氧还原反应（ORR）的电催化剂。所获得的催化剂已经通过氮吸附技术，透射电子显微镜（TEM），X射线光电子能谱（XPS）和拉曼光谱来充分表征。结合不同掺杂碳纳米管的理化性质及其催化性能，比较了各种掺杂方式，并研究了这些过程的机理。发现对具有N，S和B的双和三掺杂CNT的协同作用。
