Nitrogen Doped Carbon

Gold-palladium alloy nanoparticles decorated on nitrogen-doped carbon nanotubes (Au-Pd/N-CNT) were prepared by using polyethylene imine reduction method. Polyethylene acts as not only a stabilizing agent, but also a reducing agent, leading to nucleation and growth of nanoparticles on the N-CNT surfaces. All the N-CNT-based nanofluids show broadband absorption across the visible region and near infrared region. The Au-Pd/N-CNT nanofluids absorb more solar irradiation compared with monometallic Pd/N-CNT or Au/N-CNT nanofluid. The photo-thermal conversion efficiency of Au-Pd /N-CNT nanofluids is 62.3%, compared with 53.3% and 57% for Pd/N-CNT and Au/N-CNT, respectively. This enhancement was mainly due to the synergetic effects of N-CNT and Au-Pd alloy nanoparticles.

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.
