Abstract
Current environmental and energy issues urge the advance of stable and cost-effective porous nanostructures for highly efficient electrochemical energy conversion/storage, and gas adsorption/separation. Herein, we report a one-pot, scalable pyrolysis process for fabrication of hierarchically layer-structured porous carbons with nitrogen doping and cobalt modification (Co-N-PCs) for efficient high-pressure CO2 gas adsorption and oxygen reduction reaction (ORR). Co-N-PCs possess large specific surface areas and abundant layered macropores containing micropores and narrow mesopores, coupled with core-shell Co@C/CoOx structure. Co-N-PC 800 (synthesized at 800
