Abstract
Cross-linked, N-doped, pillared-layered porous carbons (NCs) were prepared via a one-pot, template-free pyrolysis process at 600 (NC600), 700 (NC700) and 800 °C (NC800), which have bifunctional applications in supercapacitors and environmental remediation. NC700 displays a high surface area (2118 m<sup>2</sup> g<sup>−1</sup>) and a specific capacitance of 305 F g<sup>−1</sup> at 0.2 A g<sup>−1</sup> in a two-electrode setup. The maximum energy density of NC700 was 20.4 W h/kg at a power density of 139 W kg<sup>−1</sup> and 89.1% capacitance was retained after 10000 cycles of charge-discharge at 5 A g<sup>−1</sup>. For water remediation, NC800 displayed high adsorption capacities towards flame retardant tetrabromobisphenol A (TBBPA, 372 mg g<sup>−1</sup>) and antibiotic sulfachloropyridazine (SCP, 288 mg g<sup>−1</sup>) solutions, while NC700 showed the most efficient SCP oxidation removal. These results suggest low-cost and green carbon materials as electrodes in flexible energy storage devices, metal-free adsorbents as well as catalysts for high efficient removal of emerging contaminants in aqueous solution.
