A carbon dioxide (CO2) stream reacts with an amine-modified magnetic nanoparticle in solution to form an amine-CO2 adduct. The solution that includes the amine-modified magnetic nanoparticle is heated by an external alternating magnetic field. The heat provided by the external alternating magnetic field is localized such that only the amine-CO2 adduct is heated to release the CO2, without heating the entire solution. This process helps with the capture and release of CO2 with a significantly reduced energy during the CO2 release step.
