The Internal‐External Synergy of Self‐Reconstructed C/NiFeOOH/SeO42− for Efficient and Stable Seawater Electrolysis

Advanced Science, EarlyView.
This work presents an internal‐external synergy strategy where a C@FeNi2Se4 core‐shell precursor reconstructes in to a C/FeNi2Se4/SeO42− architecture during OER. The inner C stabilizes active sites while the outer SeO42− layer repels Cl−, achieving efficient and stable seawater oxidation for over 150 h at 400 mA cm−2.

Atomic Precision CoCu Heterodimers with Pseudo‐D3h Symmetry Enable Tandem Nitrate Reduction

Advanced Science, EarlyView.
The Co─Cu heterodimer anchored on nitrogen‐doped graphene oxide substrate facilitates electrochemical nitrate reduction in alkaline medium. Co site promotes water dissociation to supply a proton, while Cu sites enhance nitrate adsorption and activation.

Harnessing Transformation of Metal‐Ligand Coordination in Dinuclear Ni(II)‐Schiff Base Coordination Polymer for Promoting Electrochemical Oxygen Evolution

Advanced Science, EarlyView.
Ni–Schiff base coordination polymer [Ni2(tmd)2]n was synthesized and applied to enhance alkaline OER by virtue of its transformation between 5‐ and 6‐coordinate Ni sites along with the spin state exchange. ABSTRACT One of the major challenges in overall water splitting is improving the sluggish kinetics of the anodic oxygen evolution reaction (OER ...
