阅读说明：本技术 一种钴氮共掺杂碳纳米笼的制备方法 (Preparation method of cobalt-nitrogen co-doped carbon nanocage ) 是由 刘惠玉 潘雪婷 刘笑妤 于 2020-08-13 设计创作，主要内容包括：本发明设计了一种钴氮共掺杂碳纳米笼的制备方法,具体为以ZIF-8结构为内核,通过种子介导生长法在其外层包裹ZIF-67的外壳。在此过程中,加入Co～(2+)和2-甲基咪唑后自发以ZIF-8为内核在外部包裹ZIF-67得到ZIF-8@ZIF-67的双金属核壳结构。进一步,在800℃的流动氮气氛围下,有机配体碳化形成多孔N掺杂材料,初步得到钴氮共掺杂碳纳米笼材料；经HCl刻蚀最终得到钴氮共掺杂碳纳米笼材料。本发明制备得到的钴氮共掺杂碳纳米笼纳米颗粒形貌良好,颗粒均一,合成方法步骤简单,重复性高,且经过形貌和尺寸调整,拥有更高的活性,在电化学、催化、生物医学、抗病毒等领域具有广泛的应用前景。(The invention designs a preparation method of a cobalt-nitrogen co-doped carbon nanocage, and particularly relates to a shell which takes a ZIF-8 structure as an inner core and wraps ZIF-67 outside the inner core by a seed-mediated growth method. During this process, Co is added 2+ And 2-methylimidazole followed by spontaneous reactionThe ZIF-8 is a bimetal core-shell structure with an inner core wrapped with ZIF-67 to obtain ZIF-8@ ZIF-67. Further, under the flowing nitrogen atmosphere of 800 ℃, carbonizing an organic ligand to form a porous N-doped material, and preliminarily obtaining a cobalt-nitrogen co-doped carbon nanocage material; and finally obtaining the cobalt-nitrogen co-doped carbon nanocage material through HCl etching. The cobalt-nitrogen co-doped carbon nanocage nanoparticles prepared by the method have the advantages of good morphology, uniform particles, simple steps of the synthetic method, high repeatability, higher activity after the morphology and the size are adjusted, and wide application prospect in the fields of electrochemistry, catalysis, biomedicine, virus resistance and the like.)
