Abstract:

The selective catalytic removal of CO 2 has great significance in environmental engineering and the chemical industry, and the development of efficient and smart materials to tackle the problems related to CO 2 pollution is commendable. Herein, we report that, by facile carbonization of a g-C 3 N 4 and chitosan mixture in N 2 , nitrogen-decorated hierarchically porous carbons (N-HPC-xs) enriched with a controllable number of basic sites could be obtained. The aggregation of the unique helix 2D carbon network of N-HPC-xs resulted in abundant formation of micro-meso-macropores in the synthesized structures, enabling high exposure and accessibility of basic sites. The outcome is excellent performance for CO 2 capture (2.05-3.38 mmol g -1 at 0 °C, 1.0 bar, and 1.52-2.61 mmol g -1 at 25 °C, 1.0 bar) with high IAST (ideal adsorbed solution theory) CO 2 /N 2 selectivity (83.8-111.3 at 0 °C and 71.2-88.2 at 25 °C). Meanwhile, the loading of Co 2+ or Zn 2+ to N-HPC-xs would result in formation of novel metal@N-HPC-xs catalysts that show superior catalytic effect in CO 2 cycloaddition with epoxides at atmospheric pressure to afford cyclic carbonates. It is demonstrated that the N-HPC-xs and the catalysts derived from them have bright prospects for the capture and utilization of CO 2 originated from industrial activities. © 2019 American Chemical Society.
