Abstract Conversion of CO 2 into value‐added chemicals and fuels provides a direct solution to reduce excessive CO 2 in the atmosphere. Herein, a novel catalytic reaction system is presented by coupling the dehydrogenation of glucose with the hydrogenation of a CO 2 ‐derived salt, ammonium carbonate, in an ethanol–water mixture. For the first time, the hydrogenation of CO 2 to formate by glucose has been achieved under ambient conditions. Under the optimal reaction conditions, the highest yield of formate reached approximately 46 %. We find that the apparent pH value in the ethanol–water mixture plays a central role in determining the performance of the hydrogen‐transfer reaction. Based on the 13 C NMR and ESI–MS results, a possible pathway of the coupled glucose dehydrogenation and CO 2 hydrogenation reactions was proposed.
