  1. Purity and specific surface area (except C60) were provided by the manufacturer. The size was provided by the manufacturer and examined with a transmission electron microscope. Zeta potential was examined with Zetasizer Nano-ZS90. GNS, graphene nanosheet; NG, graphite nanoparticle; ND, diamond nanoparticle; C60, fullerene C60; MWNT, multi-wall nanotube; CVD, chemical vapour deposition. aTaken from Cheng et al. [16].
