We report on a one-step method for preparing nitrogen doped (N-doped) meso-/microporous hybrid carbon material (NCF) via the heat treatment of used cigarette filters under a nitrogen-containing atmosphere. The used cigarette filter, which is mostly composed of cellulose acetate fibers, can be transformed into a porous carbon material that contains both the mesopores and micropores spontaneously. The unique self-developed pore structure allowed a favorable pathway for electrolyte permeation and…
