Abstract Developing low‐cost and exceedingly efficient electrocatalysts for oxygen evolution reaction (OER) is vital application of hydrogen production from water splitting. Herein, three different nickel sulfides on foam were fabricated via a simple sulfuring the as‐formed Ni‐MOF with sulfide as sulfur source. The effect source OER performance, morphology structure as‐prepared product are well discussed. optimized Ni‐MOF/NF‐SS deliver overpotentials 253 330 mV to reach current densities 10 100 mA cm −2 small Tafel slope 70.9 mVdec −1 , stability over 50 h. This work provides insights into relationship between activity structures sulfides, but also affords new route fabricate sulfides‐based OER.
