▎ 摘　　要

NOVELTY - Holey graphene nanoplatelets are fabricated by subjecting partially oxidized graphite intercalation compounds (PO-GICs), oxygen intercalated graphite intercalation compounds (OI-GICs), or commercial expandable graphite (CEG) to microwave irradiation treatments to obtain holey graphene nanoplatelets, which comprise greater than or equal to 1 expanded graphene sheets having a set of holes on the basal planes. USE - Fabrication of holey graphene nanoplatelets for electrodes of batteries or electrodes of capacitors (claimed). ADVANTAGE - The method does not involve any toxic reagents or metal-containing compounds and does not generate toxic by-products, enabling a variety of eco-friendly applications.
