▎ 摘　　要

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 mesomacropores 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.
