Three-dimensional scaffolding framework of porous carbon nanosheets derived from plant wastes for high-performance supercapacitors

In this work, using dry elm samara as the prototype, we demonstrate that three-dimensional scaffolding frameworks of highly porous carbon nanosheets can be derived from plant wastes having specific natural morphology, i.e. half-transparent thin flakes, through a facile carbonization and activation treatment
