To tackle the issues of high cost, low durability and poor resistance to chemical poisoning of Pt-based materials as cathode catalysts for an oxygen reduction reaction (ORR), an effective method is to design and synthesize heteroatom doped carbon materials, regarded as promising electrocatalysts to replace Pt-based counterparts, due to their low cost, high stability and anti-poisoning ability. The potential of N, B co-doping has been proved by theoretical calculations, and there are still great challenges in the synthesis of such materials. Here, we employ a facile approach to obtain a N, B co-doped carbon material. The resulting material pyrolysed at 1000 °C (NBC-1000) shows excellent ORR activity, exceeding that of the same type of catalysts reported so far. Not only is the NBC-1000 electrocatalyst comparable to the commercial Pt/C in terms of the onset potential, half-wave potential, diffusion limiting current density and electron transfer number, but also it has better durability and methanol tolerance than Pt/C.

氮和硼共掺杂的无金属碳电催化剂，可实现有效的氧还原反应†

为了解决Pt基材料作为氧还原反应（ORR）阴极催化剂的成本高，耐久性差和耐化学中毒性差的问题，一种有效的方法是设计和合成杂原子掺杂的碳材料，被认为是有前途的电催化剂。由于其低成本，高稳定性和抗中毒能力，可替代基于Pt的对等物。理论计算已经证明了N，B共掺杂的潜力，并且在这种材料的合成中仍然存在很大的挑战。在这里，我们采用一种简便的方法来获得N，B共掺杂的碳材料。在1000°C（NBC-1000）下热解的所得材料显示出优异的ORR活性，超过了迄今为止报道的相同类型的催化剂。
