华东理工大学王庚超课题组--电泳-微波合成硫和氮掺杂石墨烯泡沫用于高性能超级电容器

杂原子掺杂石墨烯的三维自支撑结构是超级电容器的理想电极材料。然而，简易控制其组成和结构仍然是一个挑战。这里报道了一种新的电化学-凝固型电泳沉积方法，包括气泡模板法和原位微波还原过程，在超薄石墨纸上可控制备了硫、氮掺杂的石墨烯泡沫(dGF)。dGF材料拥有相互交错的孔结构，高的比表面积，以及硫和氮共掺杂，显示出高的比电容达354 F·g-1，以及良好的倍率性能。由于石墨纸作为沉积基底和原位微波还原引发剂的优点，通过定制石墨纸的形状可以方便地获得叉指电极。组装的柔性超级电容器的能量密度为71.5 W h kg-1（功率密度为0.65 kW kg-1），并且在10 000次充放电循环后仍能保持99.5%的比电容。该研究为构建石墨烯自支撑结构提供了一种理想的工艺流程，在催化、储能和环保方面具有潜在的应用价值。
