A new strategy to tailor the structure of sustainable 3D hierarchical porous N-self-doped carbons from renewable biomass for high-performance supercapacitors and CO₂ capture

Abstract

A new method was employed to obtain 3D hierarchical porous N-self-doped carbons with different porous structures from chitosan for high-performance supercapacitors and CO₂ capture without using porogens, catalysts or activators.
