Cyclopentazolate anions (cyclo-N5) have been receiving ever-increasing attention as component of energetic explosives since recent fulfilment of the first stable sample in solid phase and ambient conditions. Herein, we present a new strategy to utilize deflagration reactions of cobalt pentazolate in combination with explosive poly(ionic liquid) (EPIL) for the preparation of Co@N-doped carbon materials with homogeneously distributed cobalt nanoparticle encapsulated by the layers of N-doped carbon sheets. The resultant 5%Co (N5)2-EPIL-900 exhibits high electrocatalytic activities, excellent stability and tolerance to CH3OH towards oxygen reduction reaction (ORR). Moreover, the present approach provides a novel routine for preparation of functional materials from energetic and newly-emerging cyclo-N5-derived compounds.

自首例含有五唑阴离子(cyclo-N5)的稳定固态聚氮化合物被报道以来, 探索新兴五唑化合物的制备与应用吸引着科学家们的极大兴趣. 本文发展了一种以五唑化钴与含能聚离子液体为前驱体, 利用独特的爆燃反应制备钴修饰氮掺杂碳材料的新方法. 凭借前驱体的含能特性, 所得材料具有典型的核-壳纳米结构, 氮掺杂碳层包裹的钴纳米颗粒分布均匀. 材料5%Co(N5)2-EPIL-900在氧还原反应中展现出优异的电催化性能、稳定性和抗甲醇毒化能力. 本工作为以含能五唑化合物为前驱体高效制备功能碳材料提供了新途径.
