- •
A new route could convert corn starch to high-performance porous carbon.
- •
This new route coupled with hydrothermal carbonization and H3PO4 chemical activation.
- •
The porous carbon presented a specific surface area as large as 1239 m2 g−1.
- •
The specific capacitance of the porous carbon was as high as 144 F g−1 at 0.625 A g−1.
