Shape and phase controlled synthesis of mesostructured carbon single crystals through mesoscale self-assembly of reactive monomicelles and their unprecedented exfoliation into single-layered carbon nanoribbons.

Here we reported the synthesis of previously unreported lamellar mesostructured phloroglucinol-formaldehyde lozenge single-crystal sheets, which can be morphology-preserved thermal transformed into graphene-like layered carbons and even further be exfoliated into unprecedented high-quality single-layered carbon nanoribbons, this approach is readily scalable and thus possesses great promising in electrocatalysis, supercapacitor and battery applications.
