Carbon nanostructures synthesized from metal organic framework (MOF) precursors are rapidly emerging as attractive materials in a wide range of applications like batteries, super-capacitors, sensors, water treatment, etc. But the process of transformation of MOFs into MDC by calcination or carbonization or pyrolysis often requires inert atmospheres, long reaction times and high temperatures. Therefore there is a need for development for faster and facile synthesis of MDC from MOF precursors. In this work, we report the transformation of 2,2′-bipyridine based MOFs into iron nitride nanoparticles embedded in nitrogen-doped carbon nanotubes, fast and facile microwave pyrolysis. By using graphene oxide and carbon fiber as functional surfaces, three-dimensional nitrogen-doped carbon nanotubes vertically grown on reduced graphene oxide (MDNCNT@rGO) and carbon fibers (MDCNT@CF), were obtained. The utility of MDNCNT@rGO as electro-catalysts in ORR and MDCNT@CF in water treatment is reported. |
