Ultra-high surface area mesoporous carbons for colossal pre combustion CO2 capture and storage as materials for hydrogen purification

Abstract

Mesoporous carbons (with up to 95% of pore volume from mesopores) with surface area and pore volume of ∼4000 m² g⁻¹ and ∼3.6 cm³ g⁻¹, respectively, are excellent CO₂ absorbers under pre combustion conditions and can store 55 mmol g⁻¹ (i.e., 2.42 g g⁻¹) or 930 g l⁻¹ at 25 °C and 50 bar.
