▎ 摘  要

Two-dimensional (2D) layered carbon heterostructures with controlled porosity and high graphitic degree have attracted considerable attention in recent years. They provide a crucial role in optimizing the overall performance of different devices in various applications. Here, we have introduced a practical approach utilizing reduced graphene oxide (rGO) and metal-organic framework (MOF) synergy to achieve 2D nanoporous highly graphitic carbons. These hybrid materials have been employed for supercapacitor application and have exhibited an similar to 5-fold increase in capacitance (334 F g(-1)) compared to bare graphene oxide (GO) precursors. The symmetric supercapacitor device performance shows the highest specific energy of 17.6 Wh kg(-1) and specific power of 25000 W kg(-1) in an ionic liquid electrolyte (1-butyl-3-methylimidazolium tetrafluoroborate [bmim][BF4]). The high carbon content without any impurities provides a good retention of 97.24% up to 10000 cycles. This strategy provides a versatile route for developing various multilayered electrode materials on a large scale.
