“…It was found that the CO 2 adsorption process was physical, exothermic, and spontaneous at lower temperature. Another adsorbent organobentonite was fabricated by Ye et al 2 by microwave‐assisted heating to adsorb phenol. They found that the adsorption performance of bentonite was enhanced after functionalizing with organic modifier Dihexadecyldimethylammonium Bromide (D1621).…”
