An amine hybrid resorcinol-formaldehyde/silica composite aerogel (AH-RFSA) was developed for the first time through a solvothermal-assisted sol-gel process combined with supercritical drying (SCD). The CO2 adsorption performances of AH-RFSA in air were investigated. The results reveal that the solvothermal temperature negatively affects the CO2 adsorption capacity of AH-RFSA. Water favors the CO2 adsorption capacities, especially the useful CO2 adsorption capacity. The total CO2 adsorption capacity achieved with the new adsorbent at 25 degrees C in dry and humid air is 1.80 and 2.57 mmol g(-1), respectively. The useful CO2 adsorption capacity of AH-RFSA in humid air is as high as 1.85 mmol g(-1). The adsorbent preparation method is inspiring and the resulting adsorbent is exceptional in capacity and regenerability.
