A new aerogel based CO2 adsorbent developed using a simple sol–gel method along with supercritical drying

Abstract

A new, highly capable and dynamic aerogel adsorbent for CO₂ capture was developed using a one-step sol–gel process along with solvent exchange and supercritical drying. The highest CO₂ adsorption capacity in a 1% CO₂ flow stream (5.55 mmol g⁻¹) is much higher than other aerogel adsorbents obtained using a 10% or even higher CO₂ gas mixture.
