采用“黑面包反应”和热退火相结合的方法，在NH3气氛下成功制备了氮掺杂多孔碳颗粒（N-PCPs）。该方法简单易行，适合大规模生产，将加速无金属电催化剂的商业化进程。由于高比例的吡啶氮原子和大的BET表面积（高达657.8 m2 g −1），所得N-PCP-800在碱性和酸性介质中显示出良好的催化活性、更长的耐久性和对甲醇更好的耐受性。本研究可提供简便，但有效的和通用的方法，以成本效益和大规模生产的N-PCPs作为燃料电池（FC）的无金属氧还原反应电催化剂。
We successfully synthesized the nitrogen-doped porous carbon particles (N-PCPs) by using a combined “black bread reaction” with thermal annealing in the presence of NH3atmosphere. The method is very simple and practical for mass production, which will speed up as metal-free electrocatalyst commercialization. The resulting N-PCPs-800 shows decent catalytic activity, longer durability and better tolerance to methanol in alkaline and acidic media due to the high proportion of pyridinic nitrogen atoms and large BET surface area (up to 657.8 m2g−1). This study can provide facile but efficient and versatile approaches to cost-effective and large-scale production of N-PCPs as metal-free oxygen reduction reaction electrocatalysts for fuel cells (FCs).
