One-step synthesis of nitrogen-doped graphene-like meso-macroporous carbons as highly efficient and selective adsorbents for CO2 capture

Abstract

Graphene-like meso-macroporous carbons (GMCs) with high nitrogen contents and controllable nitrogen sites were synthesized by one-step carbonization of dicyandiamide or melamine with glucose. The unique layered structure and the presence of abundant meso-macropores in GMCs largely enhance the degree of exposure and accessibility of anchored nitrogen sites to CO₂, which provides the GMCs with excellent performance for the selective capture of CO₂.
