Abstract

A combined hydrothermal and activation process that uses hemp bast fiber as the precursor to achieve graphene-like carbon nanosheets, a carbon nanosheet including carbonized crystalline cellulose, a carbon nanosheet formed by carbonizing crystalline cellulose, a capacitative structure includes interconnected carbon nanosheets of carbonized crystalline cellulose, a method of forming a nanosheet including carbonizing crystalline cellulose to create carbonized crystalline cellulose. The interconnected two-dimensional carbon nanosheets also contain very high levels of mesoporosity.
