摘要:N-doped hierarchical carbon spheres have been synthesized via a soft template and hydrothermal method using melamine as a nitrogen source. The obtained carbon spheres possess a high nitrogen content and well-developed porosity. These carbon spheres are examined as absorbents for CO2 capture and as electrode materials for super-capacitors. Due to the high nitrogen content and hierarchical pore size distribution, the carbons show high CO2 uptakes of 2.2-4.4 mmol g(-1) at 298 K and 1 bar. Furthermore, we observe that the carbon spheres exhibit excellent performance as supercapacitor electrodes with a high specific capacitance of 356 F g(-1) at a current density of 0.2 A g(-1). These carbon spheres as promising materials will exhibit excellent performance in various fields.
