Solvent-driven electron trapping and mass transport in reduced graphites to access perfect graphene.

Nature communications

Vecera P, Holzwarth J, Edelthalhammer KF, Mundloch U, Peterlik H, Hauke F, Hirsch A.
PMID: 27506380
Nat Commun. 2016 Aug 10;7:12411. doi: 10.1038/ncomms12411.

Herein, we report on a significant discovery, namely, the quantitative discharging of reduced graphite forms, such as graphite intercalation compounds, graphenide dispersions and graphenides deposited on surfaces with the simple solvent benzonitrile. Because of its comparatively low reduction potential,...
