Abstract Introducing interstitial light atoms shows great potential in improving the intrinsic activity and stability of metal catalysts owing to strongly affecting electronic structure adsorption properties. However, filling atomically dispersed into lattices further unveiling their effects are still limited by tightly arranged lattices. Herein, study reports a calcination reduction assisted trace strategy form series single filled Co‐based (Co‐X@NF, X = P, N NF nickel foam), therefore constructing monometallic atomic interfaces between P‐coordinated Co δ+ 0 promote alkaline hydrogen evolution reaction (HER). Noteworthy, optimal Co‐P 0.43 @NF with rich interfacial very high turnover frequency values (5.64 s −1 ), which is close noble level far exceeds non‐noble catalysts. Meanwhile, it maintains excellent 150 h at 100 mA cm −2 . Theoretical studies prove that promotes H 2 O dissociation optimizes H* energy, thus forming highly active interfaces, greatly accelerates HER kinetics.

Abstract Hydrogen production from electrolysis of seawater is considered one the most promising endeavors. However, complexity environment (corrosion‐prone, slow kinetics, and side reactions such as precipitation generation) leaves much room for progress in research on efficient stable catalysts. In recent years, order to improve technology hydrogen electrolytic seawater, scientists have focused preparation catalysts design electrolytes, which has resulted important progress. further understand current status development prospects evolution reaction (HER), this article summarizes general rules electrocatalysts electrolytes HER years.
