通过简单的水热过程将C6o分子引入石墨烯片层,可控制备了具有三维多孔结构的全碳C60/石墨烯杂化材料,该材料作电极材料时电容性能得到明显提高.研究表明,C60分子和石墨烯骨架中的碳六元环之间的共轭相互作用有利于C60与石墨烯在高压水热条件下自组装形成三维多孔结构.C60分子的加入使杂化产物具有优化的多孔结构和更多的氧化还原活性位点,这赋予杂化产物优异的电化学性能.以浓度为6 mo1/LKOH溶液作为电解质,当电流密度为1A/g时,其比电容为332.3 F/g,与三维多孔结构石墨烯材料电极相比提高了54.5％.此外,作为完全由碳原子组成的复合电极材料,其表现出的电化学性能优于文献报道的类似碳基材料.这一研究表明全碳杂化电极材料在用于制造高性能超级电容器方面具有很强竞争力和广阔应用前景,为未来基于全碳电极的高性能储能器件的设计和制备提供了有价值参考.“,”Control of the three-dimensional (3D) pore structure of all-carbon C60/graphene hybrids was conducted by introducingrn C60molecules into graphene laminates by a simple hydrothermal method to improve their performance as electrodes in supercapaci-tors. Results indicate that the strong π-π interaction between carbon hexagons in C6 and graphene skeletons favors the self-assembly of the 3D pore structure of the C60/graphene hybrids under hydrothermal conditions. The addition of C60 molecules gives the hybrids a hierarchical pore structure and redox-active sites, which contribute remarkably to the improved electrochemical performance. A specific capacitance of 332. 3 F·g-1 at a current density of 1 A·g-1 was obtained in a 6 mol-L-1 potassium hydroxide solution for a hybrid optimized by an orthogonal experimental design method, which is 54. 5％ higher than that of the graphene without C60. This finding indicates that the all-carbon hybrids may be used as more competitive and promising electrodes for the fabrication of high per-formance supercapacitors.
