摘要

Due to the unique physical and chemical merits including excellent electrical conductivity,superior chemical stability,and tunable carbon framework,two-dimensional (2D) porous carbon nanosheets have drawn increasing research interest and demonstrated promising potentials in various applications.However,regulating the nanostructure of 2D porous carbon nanosheets by facile and efficient strategies remains a great challenge.Herein,we develop a new strategy to construct Fe,N-codoped hierarchical porous carbon nanosheets (Fe-N-HPCNS)by using 2D Fe-Zn layered double hydroxides (Fe-Zn-LDH) as multifunctional templates.Fe-Zn-LDH could functionalize not only as 2D structure directing agents but also as ternary hierarchical porogens for micro-,meso-and macropores and in situ Fe dopants.This multifunctional templating strategy toward 2D porous carbon nanosheets can improve the utilization of templates and shows great advantages against conventional procedures that additional porogens and/or dopants are often needed.
