在本文中，我们报道了一种在空气气氛下利用微波辐射结合自活化策略超简便地制备磷掺杂蛋形多孔碳的方法。与传统的热解碳化方法相比，报道的方法具有能量效率高、超快和无惰性气氛保护等优点，无需制造工艺。在惰性气氛保护下，仅需3min的微波辐射法即可获得与传统热解炭化方法制备的样品相似的形貌和石墨化程度。用报道的方法制备的样品具有独特的掺磷蛋状层状多孔结构，高比表面积(1642cm2g−1)和大孔容(2.04cm3g−1)。所报道的方法制备的样品的比电容高达209F g−1，并且随着电流密度从0.5A增加到20A g−1，初始电容保持了96.2%以上，表明所制备的样品具有优异的电容性能。层次化的多孔结构、开放的微孔结构、额外的伪电容、高的电解液可及表面积和良好的导电性是其优异的电容性能的关键因素。
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 m2g−1) and large pore volume (2.04 cm3g−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 microporosity, additional pseudocapacitance, high electrolyte-accessible surface area and good conductivity make essential contribution to its superior capacitance performance.
