虽然二维碳材料被广泛研究，但具有有序介观结构的良好定义的二维碳纳米片很少被实现。通过甲阶酚醛树脂和F127在蒙脱土（MONT）层间的限制组装，制备了单层有序介孔碳纳米片（OMCNS）。MONT的层间距仅允许甲阶酚醛树脂和F127在同一平面上组装，导致垂直于碳纳米片的有序介孔，并有利于sp（2）碳的形成，导致高石墨化度。碳纳米片上的中孔提供有效的离子扩散，并且高石墨化度提供快速的电子传输途径，使得OMCNS能够作为双电层电容器的优异电极材料。
Although two-dimensional (2D) carbon materials are widely investigated, a well-defined 2D carbon nanosheet with an ordered mesostructure has rarely been realized. Monolayer-ordered mesoporous carbon nanosheets (OMCNS) were prepared through confinement assembly of resol and F127 in the interlayer of montmorillonite (MONT). The nanoscale distance of the interlayer space of MONT only allow the assembly of resol and F127 in the same plane, leading to ordered mesopores perpendicular to carbon nanosheets, and favor the formation of sp(2) carbon, resulting in a high degree of graphitization. The mesopores on the carbon nanosheets provide efficient ion diffusion, and the high degree of graphitization provides a fast electron-transport route, enabling OMCNS as excellent electrode materials for electric double layer capacitors.
