Porous carbon materials with high surface areas were prepared using a hypercrosslinked porous organic polymer as porous precursor with potassium hydroxide activation. Nitrogen adsorption analysis revealed that the porous carbon materials have high surface area of up to 3101 m(2) g(-1) and high pore volume of 1.84 cm(3) g(-1), which can provide more accessible surface and sites for gas adsorption and electrochemical energy storage. The porous carbons with high surface area show high H-2 uptake ability of up to 3.25 wt% at 77 K and 1.13 bar and CO2 uptake ability of 6.69 mmol g(-1) at 273 K and 1.13 bar. The lithium ion battery fabricated from CHCPB-K-600 shows a high specific discharge capacity of 1221 mA h g(-1) at 100 mA g(-1), which could still retain 833 mA h g(-1) after 50 cycles at 100 mA CHCPB-K-600 also exhibits a high capacitance of 379 F g(-1) at 0.5 A g(-1) for supercapacitor, and the capacitance retains 91.2% after 3000 cycles at 2 A g(-1). Considering the high gas uptake ability, the excellent electrochemical performance, and the facile preparation strategy, these porous carbons hold a great potential for gas adsorption and energy storage.
