The present invention provides a magnetic ionic liquid nanocomposite adsorption material for CO2 capture. In the present invention, the ionic liquid containing amine groups is loaded on the surface of the nano-magnetic material carrier to form a composite material for capturing CO 2 . The amine-based ionic liquid can adsorb CO 2 in high capacity with less loss, and the nano-material can significantly improve the specific surface area and dispersion of CO 2 . Therefore, the adsorption capacity can be increased, and the magnetic material can use the magnetic field to realize the rapid and efficient recovery of the adsorbent. The invention has the advantages of high adsorption capacity, strong stability, no loss of ionic liquid, large CO2 capacity at higher temperature, fast and efficient recovery of adsorbent, etc., so it has a good prospect in the field of carbon dioxide capture . |
