dc.description.abstractWe successfully synthesize Cu 3 P nanosheets and granular Ni 2 P nanocrystals on the surface of commercial carbon fiber cloth (CFC) (Cu 3 P/CFC and Ni 2 P/CFC) respectively by a vapor-phase hydrothermal route. The as-synthesized Ni 2 P/CFC and Cu 3 P/CFC as electrodes all show the bifunctional electrocatalytic performances towards hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER), simultaneously all demonstrating the electrocatalytic activities of the furfural hydrogenation reaction (FHR) and furfural oxidation reaction (FOR) in alkaline media. Comparatively, the Cu 3 P/CFC exhibits higher FHR activity with almost ∼100% selectivity of the furfuryl alcohol (FAL) product and high Faradaic efficiency (FE) of 92.0%–98.0% over the applied potential range of −0.05 to −0.55 V (vs. RHE), while the Ni 2 P/CFC indicates higher FOR activity with almost ∼100% selectivity of furoic acid (FA) product and FE of 90.0%–98.0% at the applied potential of 1.2–1.7 V (vs. RHE) in alkaline electrolyte containing 50 mM furfural. The DFT calculations results reveal that the (1–10) dominated Cu 3 P can obtain higher hydrogen coverage but restricted H 2 desorption compared to the (001) dominated Ni 2 P, therefore the adsorbed active hydrogen (H) atoms from water can be effectively used for the FHR process, resulting in high FE and current density. The superior FOR activity of the Ni 2 P/CFC is mainly stemmed from the formed high valence state Ni species during electrocatalysis. Thanks to the superior FHR performance of Cu 3 P/CFC and FOR activity of Ni 2 P/CFC, a two-electrode H-type electrocatalysis system assembled with the Cu 3 P/CFC as cathode and Ni 2 P/CFC as anode can be constructed for simultaneously electrocatalytic production of FAL and FA with almost ∼100% selectivity in 1.0 M KOH electrolyte containing 50 mM furfural in each chamber under the given experimental conditions, demonstrating high FE of 97%–99%.
