Abstract:
Methods for a facile, template free and one-step synthesis of nanoporous carbons by using a heterocyclic aromatic organic compound as a single source precursor of both carbon and nitrogen are described. The heterocyclic aromatic organic compound contains nitrogen in pyrrolic and/or pyridinic positions and is chemically activated with NaOH, KOH or ZnCl 2  at high temperatures in a solid state mixture as a synthesis protocol to promote fine micropores during carbonization. Nanoporous carbons synthesized by these methods that have superior gas sorption/storage and energy storage properties are also described. The nanoporous carbons are useful as carbon sequestration agents and supercapacitors.

Claim (Index 19):
A benzimidazole-derived carbon comprising:\n 3-18 wt % nitrogen, 10-15% oxygen, and/or 69-84 wt % carbon; and/or at least 90% of total pores have a pore size in the range of about 0.4-8 nm; and/or a CO 2  surface excess uptake of up to about 25 mmol/g at 30 bar and 298 K; and/or an excess CO 2  adsorption capacity at 30 bar ranging from about 7-25 mmol/g; and/or a CO 2  capture capacity ranging from:\n about 0.9-2.9 mmol/g at 273 K and a pressure of about 0.1 bar, or \n about 1.2-3.5 mmol/g at 273 K and a pressure of about 0.15 bar, or \n about 0.4-1.6 mmol/g at 298 K and a pressure of about 0.1 bar, or \n about 0.6-2.03 mmol/g at 298 K and a pressure of about 0.15 bar, or \n about 0.2-0.8 mmol/g at 323 K and a pressure of about 0.1 bar, or \n about 0.3-1.06 mmol/g at 323 K and a pressure of about 0.15 bar, or \n about 5.5-8.42 mmol/g at 273 K and a pressure of about 1 bar, or \n about 3.1-5.46 mmol/g at 298 K and a pressure of about 1 bar, or \n about 1.7-3.27 mmol/g at 323 K and a pressure of about 1 bar.
