“…To date, most of the research effort has been devoted to the development of novel solid adsorbent materials with enhanced adsorption capacity and lifetime while reducing the heat of adsorption, thus lessening the energetic requirement of sorbent regeneration. Among various adsorbents, carbons, 2 zeolites, 3 and metal–organic frameworks 4 have emerged as promising adsorbents for efficient CO 2 capture and separation.…”
