Synthesis of a Carbonaceous Two-Dimensional Material

Abstract

Despite tremendous accomplishment achieved in 2D materials, little progress has been made in carbonaceous 2D material beyond graphene and graphene oxide. Here we report a 2D material of carbonaceous nanoplates (CANP). The bottom-up synthesis of CANP is green, separation-free, and massive. The nanoplates are two to three monolayers thick with an average interlayer spacing of 0.57 nm. The synthesis involves viscosity-aided two-dimensional growth of fragmented glucose derivatives, and leads to complete conversion of glucose to the 2D nanoplates. Application tests demonstrate usefulness of the affordable 2D material.
