Abstract A facile and environmentally friendly approach to produce self-doped hierachically porous carbon as electrode material for high-performance supercapacitor was demonstrated. 3D honeycomb-like hierarchically porous carbon was successfully obtained by one-step carbonization and activation of sodium carboxymethyl cellulose (CMC) via K2CO3. With the optimized temperature of carbonization and activation, the porous carbon material achieved well-shaped hierarchically pores (micro-, meso and macropores) like a honeycomb, ultrahigh specific surface area (1666 m2·g-1), as well as highly O-self-doping (3.6 at.%), endowing an excellent electrochemical properties for the electrode in three-electrode system. The porous carbon electrode material delivered a high specific capacitance of 300.8 F·g-1 at 1 A·g-1, an eminent rate capability of 228.4 F·g-1 at the current density up to 20 A·g-1 and outstanding cycle stability of 94.3% retention after 10000 cycles. Therefore, the CMC derived hierarchical porous carbon activated by K2CO3 would have promising foreground in application of supercapacitors.

The one-step synthesis of high-quality graphene derivatives via CVD process has gained considerable importance nowadays for high-performance electronics and sensors. However, the use of harsh chemicals, high temperature, sensitivity, and the problem of separation of graphene from the substrate, motivated the one-step synthesis of graphene from a non-graphitic precursor, bypassing the use of graphite. In this paper, we have reported for the first time, the synthesis of graphene nanosheets from sugarcane bagasse at the normal atmospheric condition in a single step, avoiding the formation of GO. Here, the pyrolysis of sugarcane bagasse was carried out in the temperature range of 250-450o C in the presence of sodium hydroxide. The results suggested that even the low temperature (250–450o C) facilitated the development of graphitic planes via condensation and aromatization of the glucose monomers present in the precursor. The XRD pattern showed 2θ at around 25o in each case, which confirmed the formation of graphene instead of GO. The FESEM, TEM, and EDX analysis proved the formation of few-layer nanosheets of graphene from carbon-rich waste precursors in a single step.
