Capture of CO2 in air for 4,5-disubstituted furan-2(5H)-ones†
Abstract
A highly efficient strategy for carbon dioxide capture and utilization (CCU) was applied to the synthesis of 4,5-disubstituted furan-2(5H)-ones by a Cu(I)/base catalytic system. An aqueous morpholine solution as a superior adsorbent for the capture of carbon dioxide directly from air was recycled continuously via adsorption/desorption cycles.
