HydrocarbonDerived Graphene Nanoparticles and Their Networked Morphology Academic Article uri icon

abstract

  • Over the past two decades, there has been a significant increase in the industrial production of carbon nanomaterials. Many highquality nanomaterials require the use of metalbased catalysts, which in turn raise production costs, require postprocessing, and limit scaleup. Herein, novel industrially produced graphene nanoparticles that are derived from hydrocarbon streams via a scalable catalystfree process in a proprietary reactor are analyzed. The resulting carbon nanomaterials exhibit a unique morphology, featuring nanoscale building blocks in microscale networks. The nanomaterials display exceptional performance in several applications due to their prenetworked structure: These carbon nanomaterials are promising as conductive additives for supercapacitor electrodes, which exhibit superior performance compared to common commercial additives (61% capacitance improvement at 2Ag1), and as electrochemical sensors, with a sensitivity of 162Amm1cm2 for nitrite ion sensing. Moreover, these carbon nanomaterials reinforce thermoset and thermoplastic composites, with tensile strength enhancement of 238% at 5wt% filler for epoxy, superior to prior reports for carbon nanotubes.
