An effective strategy is developed to in situ anchor metal nanoparticles into the nitrogen-doped carbon framework (MNCs) by thermal treatment of metallophthalocyanine based conjugated microporous polymers. The metal nanoparticles are uniformly distributed into the porous nitrogen-doped carbon framework and interact with N active sites, thus showing enhanced diffusion kinetics as catalysts for oxygen reduction reaction. Benefiting from the effective strategy and specific structure, the as-obtained MNCs show superior oxygen reduction reaction activity in both alkaline and acid media, and their long-time stability and methanol tolerance are superior to the commercial Pt–C. Moreover, the MNCs also display high performance as cathode catalysts for Zn–air batteries. In view of the novel synthesis process and excellent performance, the proposed strategy could open new avenues for the design of high-performance oxygen reduction reaction catalysts for energy storage and conversion.

将金属纳米颗粒原位锚定在源自共轭微孔聚合物的N掺杂碳框架中,以实现有效的氧还原反应

一种有效的策略被开发到原地通过对基于金属酞菁的共轭微孔聚合物进行热处理,将金属纳米颗粒锚固到氮掺杂碳骨架中。金属纳米颗粒均匀地分布在多孔的氮掺杂碳骨架中并与N个活性位点相互作用,因此作为氧还原反应的催化剂表现出增强的扩散动力学。得益于有效的策略和特定的结构,所获得的MNC在碱性和酸性介质中均表现出优异的氧还原反应活性,并且其长期稳定性和甲醇耐受性优于商用Pt-C。此外,跨国公司还表现出作为锌空气电池阴极催化剂的高性能。鉴于新颖的合成工艺和出色的性能,
