▎ 摘　　要

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 C-13-enriched graphitic materials, from which graphene oxides similarly enriched with C-13 were prepared and characterized. The results demonstrate that arc-discharge is a convenient method to produce bulk quantities of C-13-enriched graphene materials from relatively less expensive precursors (largely amorphous C-13 powders).
