摘      要:Metal-nanocluster materials have gradually become a promising electrode candidate for supercapaci-tor *** high-efficient and rational architecture of these metal-nanocluster electrode mate-rials with satisfied supercapacitive performance are full of ***,Fe-nanocluster anchored porous carbon(FAPC)nanosheets were constructed through a facile and low-cost impregnation-activation *** characterization methods documented that FAPC nanosheets possessed a mesopore-dominated structure with large surface area and abundant Fe-N4 active sites,which are crucial for su-percapacitive energy *** optimal FAPC electrode exhibited a high specific capacitance of 378 F/g at a specific current of 1 A/g and an excellent rate capability(271 F/g at 10 A/g),which are comparable or even superior to that of most reported carbon ***,the FAPC-based device achieved a desired specific energy of 14.8 Wh/kg at a specific power of 700 W/*** work opens a new avenue to design metal-nanocluster materials for high-performance biomass waste-based supercapacitors.
