Nanomaterials including nanoparticles, nanosheets (纳米片), nanomembranes (纳米膜), metal organic frameworks and biochar (生物炭) have gained more acceptance to use these as artificial CO2 adsorbents. Also, the organic solvents such as amine-based solvents (胺基溶剂) have also been employed for the CO2 absorption from various sources. Various ionic (离子) liquids, eutectic (共晶) solvents and organic solvents have also huge potential to absorb and convert the atmospheric CO2 and convert it into other or useful products under controlled conditions.
