Abstract
A method of carbon-capture sorbent regeneration is provided. The method includes obtaining a sorbent that includes adsorbed carbon dioxide. Magnetic nanoparticles are introduced to the sorbent and adsorbed carbon dioxide to form a mixture. A magnetic field is applied to the mixture. The magnetic nanoparticles generate heat which releases carbon dioxide from the sorbent, thereby regenerating the sorbent. The magnetic nanoparticles include iron oxides, doped ferrites, functionalized iron oxides, functionalized ferrites, and composite materials that are combinations of these. The sorbent includes liquid and solid sorbents, and the regenerated sorbent may be utilized for further carbon capture.
