The group of LIU Licheng has designed a novel yttrium oxide nanosheet/nitrogen-doped graphene quantum dot (Bi2O3). -NGQDs) composite catalyst for the efficient electrocatalytic reduction of CO2 to form formic acid. The introduction of quantum dots accelerated the charge transfer during the electrocatalytic reaction and allowed to maintain an average current efficiency of up to 95.6% over a wide negative voltage range of -0.9 V to -1.2 V (vs. RHE).
