摘要：

In this study, microporous pyropolymers (GL-AMPs), a carbon-based material, were fabricated from ginkgo leaves by simple pyrolysis with KOH, followed by acid treatment. The GL-AMPS were mainly composed of aromatic hexagonal carbon layers, which were not well stacked, and contained many redox-active heteroatoms such as oxygen and nitrogen. In addition, the GL-AMPS had a high specific surface area of similar to 1348.4 m(2)g(-1) with numerous ultramicropores (<0.7 nm). These unique material characteristics led to a significantly high specific capacitance of similar to 731 Fg(-1), high rate capabilities, and stable cycling performance over 1000 cycles in a redox-mediated aqueous electrolyte.
