Preparation of Bulk 13C-Enriched Graphene Materials

Abstract EN

Arc-discharge has been widely used in the bulk production of various carbon nanomaterials, especially for structurally more robust single-walled carbon nanotubes.

In this paper, the same bulk-production technique was applied to the synthesis of significantly 13C-enriched graphitic materials, from which graphene oxides similarly enriched with 13C were prepared and characterized.

The results demonstrate that arc-discharge is a convenient method to produce bulk quantities of 13C-enriched graphene materials from relatively less expensive precursors (largely amorphous 13C powders).
