Self-supported nickel‐cobalt layered double hydroxide for efficient primary amine electrooxidation and decoupled water electrolysis

Abstract

The hybrid water electrolysis affords a green route for the generation of fine chemicals accompanied with hydrogen production relying on the rapid development of anodic electrocatalysts. Herein, a nickel‐cobalt layered double hydroxide (NiCo LDH) modified nickel foam, prepared at room temperature via simple soaking processes, could effectively catalyze the dehydrogenation oxidation of primary amines to generate aromatic and aliphatic nitriles with good yields. Further expanding the application of the easily available electrode, the NiCo LDH electrode could function as the electron reservoir to realize the decoupled water electrolysis with 100% coulombic efficiency in the membrane-free electrolytic cell.
