One of the most relevant topics to address a “Cleaner Future” is Carbon Capture and Sequestration, where the molecule in the crosshairs of this subject is CO2 (Vaz et al., 2022). Several processes are considered in the CO2 capture, where adsorption represents a cleaner and more affordable technology (Sattari et al., 2021). Carbon materials with pore sizes from a few angstroms to a few nanometers have been highlighted among the different porous adsorbents to CO2 capture. The influence of these textural properties on CO2 adsorption needs to be studied.This work presents the synthesis and analysis of a series of carbon materials with different textural properties used in the carbon dioxide capture at 308 K and up to 10 bar. Textural properties of more than twenty nanoporous carbons obtained with varying synthesis methods were compared and correlated with the carbon dioxide uptake. This series includes biomass-based carbons with chemical or physical activation and ordered templated carbons.
