In particular, the production of CO from CO₂ has been an area of intense interest, particularly since the CO can be utilized in Fischer-Tropsch synthesis. Herein we report that CO₂ can also be used as a source of atomic oxygen that is efficiently harvested and used as a waste-free terminal oxidant for the oxidation of alkenes to epoxides. Simultaneously, the process yields CO. Utilization of the atomic oxygen does not only generate a valuable product, but also prevents the recombination of O and CO, thus increasing the yield of CO for possible application in the synthesis of higher-order hydrocarbons.Chemical scienceOxygen harvesting from carbon dioxide: simultaneous epoxidation and CO formation.PMC8528036EP/P030599/1Shaban MAlkayal AWang SKong MGPlasser FIza FXu HLiu DBuckley BR48falseOxygen harvesting from carbon dioxide: simultaneous epoxidation and CO formation.Due to increasing concentrations in the atmosphere, carbon dioxide has, in recent times, been targeted for utilisation (Carbon Capture Utilisation and Storage, CCUS).
