| Construction of MnCoNi layered double hydroxide@Co-Ni-S amorphous hollow polyhedron composite with excellent electrocatalytic oxygen evolution performance |

| Abstract: The nickel foam (NF)-supported MnCoNi layered double hydroxide (LDH) nano-needle array was used as a substrate. Through a two-step wet-chemical route, a Co-Ni-S polymetallic sulfide-supported MnCoNi LDH@Co-NiS/NF amorphous hollow-polyhedral nanocomposite was successfully synthesized, demonstrating outstanding electrocatalytic oxygen evolution performance. The results of electrochemical tests showed that the material could output a current density of 50 mA·cm-2 with an overpotential of only 248 mV in a 1.0 mol·L-1 KOH solution. In addition, the constructed MnCoNi LDH@Co-Ni-S hollow polyhedral electrode could operate continuously and stably for at least 20 h under different current densities of 40, 60, and 80 mA·cm-2, fully demonstrating that this electrode had good long-term stability. |
