Abstract
Carbon dioxide capture and release includes contacting a gas comprising carbon dioxide with a mixture comprising a precursor and a solvent and reducing the precursor to form a capture agent. The capture agent is reacted with the carbon dioxide to form a non-volatile species containing carbon dioxide. The non-volatile species is oxidized to regenerate the precursor and to release carbon dioxide. The mixture may be formed by combining the precursor and the solvent.
