“…Herein, furfural has been recognized as a renewable feedstock for biomass‐derived intermediates such as chemicals, medicines, polymers, and liquid fuel. [ 4 ] However, direct utilization of furfural conversion into value‐added products is still the limitation of upgrading technologies and the lack of economic performance. Electrocatalytic oxidation of furfural is an efficient strategy for biomass upgrading and hydrogen production under ambient conditions.…”

Electrocatalytic biomass upgrading has proven to be an effective technique for generating value‐added products. Herein, the design and development of furfural upgrading using transition‐metal borides (MBenes) with simultaneous production of hydrogen are presented. Using density functional theory, the stabilities, selectivities, and activities of 13 MBene candidates are systematically evaluated for furfural upgrading. This research suggests that Fe2B2 can serve as a promising electrocatalyst for the formation of furoic acid (FAC), with a limiting potential of −0.15 V, and 5‐hydroxy‐2(5H)‐furanone (HFO), with a limiting potential of −0.93 V. Furthermore, Fe2B2 and Mn2Fe2 are shown to exhibit favorable limiting potentials of −1.35 and −1.36 V, respectively, for producing 6‐hydroxy‐2.3‐dihydro‐6H‐pyrano‐3‐one (HDPO), indicating that they may also serve as electrocatalysts. Based on Sabatier's principle, a descriptor (φ) of material properties is developed for screening catalysts with high catalytic activity considering the electronegativities and d‐electron number of metals. Additionally, surface redox potential, electronic properties, and charge‐density differences are determined for Fe2B2, which is estimated to exhibit high catalytic activity for the oxidation of furfural to FAC and HFO.
