Metal organic framework (MOF)-derived carbon nanostructures (MDC) synthesized by either calcinations or carbonization or pyrolysis are emerging as attractive materials for a wide range of applications like batteries, super-capacitors, sensors, water treatment, etc. But the process of transformation of MOFs into MDCs is time-consuming, with reactions requiring inert atmospheres and reaction time typically running into hours. In this manuscript, we report the transformation of 1,4-diazabicyclo[2.2.2]octane, (DABCO)-based MOFs into iron nitride nanoparticles embedded in nitrogen-doped carbon nanotubes by simple, fast and facile microwave pyrolysis. By using graphene oxide and carbon fiber as microwave susceptible surfaces, three-dimensional nitrogen-doped carbon nanotubes vertically grown on reduced graphene oxide (MDNCNT@rGO) and carbon fibers (MDCNT@CF), respectively, were obtained, whose utility as anode material in sodium-ion batteries (MDNCNT@rGO) and for EMI (electromagnetic interference) shielding material (MDCNT@CF) is reported.
金属有机骨架（MOF）衍生的碳纳米结构（MDC）通过煅烧、碳化或热解合成，作为电池、超级电容器、传感器、水处理等各种应用的有吸引力的材料而崭露头角。但是，MOF 转化为 MDC 的过程很耗时，反应需要惰性气氛，反应时间通常需要数小时。在本文中，我们报告了通过简单、快速和简便的微波热解，将基于 1,4-二氮杂双环[2.2.2]辛烷（DABCO）的 MOF 转化为氮掺杂碳纳米管内嵌入的氮化铁纳米粒子。通过使用氧化石墨烯和碳纤维作为微波敏化表面，分别获得了垂直生长在还原氧化石墨烯（MDNCNT@rGO）和碳纤维（MDCNT@CF）上的三维氮掺杂碳纳米管，报道了它们作为钠离子电池（MDNCNT@rGO）的阳极材料和 EMI（电磁干扰）屏蔽材料（MDCNT@CF）的用途。
