Macro–microporous carbon for supercapacitors derived from rape seed shell

---

Abstract.
In this work, a novel macro–microporous architecture is successfully constructed in a honeycomb-like
structure by directly using rape seed shell via impregation-activation route. This approach permits the
high specific surface area (SSA) and a unique hierarchical porous structure which consists of
interconnected macroporous skeleton and a significant microporosity. The unique honeycomb-like
network combined with high specific surface area is favorable for charging the electric double-layer.
The resulting carbon is highly suitable as electrodes of electric double layer capacitors, with remarkable
values of capacitance of up to 225 F g−1 at a current density of 1 A g−1 in 2 M KOH electrolyte. Therefore,
the as-prepared carbon can be a potential candidate for supercapacitors.
