摘要 | Herein, we report an ultra-facile fabrication method for a phosphorus doped egg-like hierarchic porous carbon by microwave irradiation combining with self-activation strategy under air atmosphere. Comparing with the traditional pyrolytic carbonization method, the reported method exhibits incomparable merits, such as high energy efficiency, ultra-fast and inert atmosphere protection absent fabrication process. Similar morphology and graphitization degree with the sample fabricated by the traditional pyrolytic carbonization method under inert atmosphere protection for 2 h can be easily achieved by the reported microwave irradiation method just for 3 min under ambient atmosphere. The samples fabricated by the reported method display a unique phosphorus doped egg-like hierarchic porous structure, high specific surface area (1642 m(2) g(-1)) and large pore volume (2.04 cm(3) g(-1)). Specific capacitance of the samples fabricated by the reported method reaches up to 209 F g(-1), and over 96.2% of initial capacitance remains as current density increasing from 0.5 to 20 A g(-1), indicating the superior capacitance performance of the fabricated samples. The hierarchic porous structure, opened micro porosity, additional pseudocapacitance, high electrolyte-accessible surface area and good conductivity make essential contribution to its superior capacitance performance. |
