The interconnected open-channel carbon nanosheets were prepared from the agro-waste pineapple leaf fiber using a simple hydrothermal technique and KOH chemical activation under heat treatment in Ar atmosphere. The obtained activated carbon showed amorphous structure with porous graphitized carbon nanosheets and a high specific surface area of 1681 m2g−1. When used as an active material for supercapacitor, such natural fiber-derived carbon nanosheets revealed a high electrochemical performance (the specific capacitance was as high as 202 F g−1at 5 mV s−1in 1 M H2SO4) and a superb cycling stability even after 10,000 cycles of operation. The carbon nanosheets reported herein, therefore, represent a green energy material that combine the benefit of sustainability of an active component and the promise of high-performance energy storage device.Mahidol UniversityAgricultural and Biological SciencesArticleSCOPUS10.1016/j.indcrop.2017.04.015
