A series of carbon aerogels were synthesized by polycondensation of resorcinol and formaldehyde using cetyltrimethyl ammonium bromide (CTAB) as a catalyst. The structure and properties of carbon aerogels were characterized by X‐ray diffraction (XRD), Raman, scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT‐IR), and N 2 adsorption‐desorption technologies. Besides, the CO 2 capture behavior of carbon aerogels was also investigated. It was found that the amount of CTAB affected the structure and morphology of carbon aerogels, thus influenced the CO 2 adsorption behavior. The sample CA‐125 (the ratio of resorcinol and CTAB is 125) had the highest CO 2 adsorption capacity (63.71 cm 3 · g –1 at 1 bar and 24.14 cm 3 · g –1 at 0.15 bar) at 25 °C. In addition, the higher CO 2 adsorption capacity was ascribed to the higher surface area, pore volume and appropriate pore size, as well as the more defects over carbon aerogels.
