Research Abstract

Zigzag-edge nanographene can be a promising magnetic material, which contributes to the magnetic separation and collection of minor metals. In this study, we developed a novel scalable production method of zigzag-edge-introduced nanographene by combination between anisotropic etching and supercritical fluid exfoliation.
We conducted anisotropic etching of graphite substrate/powder with catalytic nanoparticles in supercritical water. Anisotropic etching made a lot of trenches consisted of zigzag edges on graphite surface. Because of the exfoliation effect of supercritical fluid, graphene was isolated from the graphite simultaneously with the anisotropic etching. Finally, the multilayer graphene with zigzag edge was exfoliated from the anisotropically etched graphite surface.
