High-Yield Continuous-Flow Synthesis of Spheroidal C(60)@Graphene Composites as Supercapacitors
[Image: see text] Graphene spheres confining fullerene C(60) are quantitatively formed under high-shear and continuous-flow processing using a vortex fluidic device (VFD). This involves intense micromixing a colloidal suspension of graphite in DMF and an o-xylene solution of C(60) at room temperatur...

description | [Image: see text] Graphene spheres confining fullerene C(60) are quantitatively formed under high-shear and continuous-flow processing using a vortex fluidic device (VFD). This involves intense micromixing a colloidal suspension of graphite in DMF and an o-xylene solution of C(60) at room temperature in the absence of surfactants and other auxiliary substances. The diameters of the composite spheres, C(60)@graphene, can be controlled with size distributions ranging from 1.5 to 3.5 μm, depending on the VFD operating parameters, including rotational speed, flow rate, relative ratio of C(60) to graphite, and the concentration of fullerene. An electrode of the composite material has high cycle stability, with a high areal capacitance of 103.4 mF cm(–2), maintaining its capacitances to 24.7 F g(–1) and 86.4 mF cm(–2) (83.5%) at a high scan rate of 100 mV s(–1). |
