The energy crisis and environmental pollution have forced scientists to explore alternative
energy conversion and storage devices. The anodic reactions of these devices are all oxygen
evolution reactions (OER), so the development of efficient OER electrocatalysts is of great
significance. At the same time, understanding the reaction mechanism of OER is conducive to
the rational design of efficient OER electrocatalysts. In general, catalytic active centers
play a direct role in OER performance. In this paper, a series of stable bimetallic metal-
organic frameworks (MOFs, named as Fe-3-Co-n-X-2, n=2, 3 and X=F, Cl, Br) with similar
structure were synthesized by changing the halogen coordinated with the cobalt metal active
center, aiming to investigate the influence of halogen substitution effect on OER
performance. It was found that the OER activity of Fe-3-Co-3-F-2 is much better than Fe-3-
Co-2-Cl-2 and Fe-3-Co-2-Br-2, indicating that the regulation of the electronegativity
change of the coordination halogen atom can regulate the coordination electron structure of
the metal active center, thereby achieving effective regulation of OER performance.
