• Resumen

  • Porous carbons are promising adsorbents for CO2 adsorption owing to their large surface area, easy-to-design pore structure, ready availability, tunable surface chemistry, and low energy requirements for regeneration. In this chapter, the potential of porous carbons for carbon capture in different scenarios will be shown. Firstly, the fundamentals of CO2 adsorption by porous carbons will be thoroughly described. Afterward, the synthesis strategies developed so far for the synthesis and control of the textural and chemical characteristics of porous carbons from a variety of precursors will be reviewed in combination with a comprehensive analysis of the performance of the materials produced in CO2 capture at low and high pressure. Traditional activation approaches will be discussed, with reference to recent advances that have allowed a wider control over the textural properties of the materials produced. More recent developments in carbon synthesis will also be discussed, such as nanocasting approaches, carbide-derived carbons, MOF-/COF-derived carbons, and novel polymerization approaches such as the use of deep eutectic solvents (DES).
