摘　　要：石墨炔是完全具有中国自主知识产权的全碳材料,在催化、能源、电子器件等诸多领域具有潜在应用。通过设计并合成不同的反应前体,经过炔炔偶联反应制备石墨炔碳材料。对材料进行Raman、XRD、XPS、SEM、TEM等结构与形貌表征,实现了石墨炔多孔碳材料掺杂氮原子的含量(3%~17%)及位置可控(吡啶氮/三嗪氮)。对材料的氧还原催化性能及锂电性能进行研究,验证了石墨炔碳材料在催化及储能方面的优势。Graphdiyne is an all carbon material with Chinese independent intellectual property rights, which has potential applications in catalysis, energy, electronic devices and many other fields. Through the design and synthesis of different precursors, different kinds of graphdiyne are prepared by the acetylene coupling reaction.Through the characterization of the composition and morphology by Raman, XRD, XPS, SEM and TEM, it is demonstrated that the N-content(3%~17%), and N-configurations of graphdiyne show good controllability. As a non-metal catalyst, its outstanding electrochemical performance in catalyzing the oxygen reduction reaction and in lithiumion batteries extend the material for new energy fields.
