摘要

Abstract

Increasing active sites and improving long-term stability are of great significance for electrocatalysts in water splitting. Herein

we report a simple and metal-economize synthesis of NiFe-LDH@Ni-MOF/NF (Nickle iron layered double hydroxide@Nickle metal-organic frameworks/Nickel foam) heterostructures. The NiFe-LDH@Ni-MOF/NF electrocatalyst possesses ultralow oxygen evolution overpotentials of 205

231

and 248 mV at current densities of 10

and 100 mA cm

–2

respectively

with a small Tafel slope of 43.7 mV dec

−1

benefiting from the exposure of edge defects and catalytic active sites

and reduced diffusion pathways for mass and charge transfer

making it one of the best non-noble-metal-based electrocatalysts for oxygen evolution.
