Abstract Owing to the presence of a substantial concentration chlorine in seawater, anode still faces severe corrosion, especially water splitting operated at high current densities. Herein, cost‐effective and scalable NiFe layered double hydroxides with carbonate intercalation (named as LDH_CO 3 2− ) are synthesized utilizing etching‐hydrolysis ion exchange strategies under ambient conditions. Experimental findings demonstrate that shows excellent stability 500 1000 mA cm −2 for h alkaline simulated seawater. Additionally, two‐electrode system offers great densities ranging from 100 over duration 400 This remarkably catalytic can be ascribed strategies. The strategy leads an integrated electrode catalyst‐carrier, enhancing adhesion between them, retarding hence divorce catalysts carrier. Theoretical calculations suggest weakens adsorbability on hinders coupling metal atoms chlorine, thereby impeding corrosion caused by improving stability. More importantly, this has been extended preparation other intercalation.

Abstract The electrocatalytic performance of MoNi‐based nanomaterials undergo selenization has garnered significant interest due to their modified electronic structure, while still posses certain challenges for obtained bimetallic selenides. Here, a novel electrocatalyst NiMoO 4 @Mo 15 Se 19 /NiSe 2 core‐shell is constructed promote the desorption OOH * which can facilitate water oxidation process. nanoarrays show that “cores” are mainly nanorods “shells” selenides nanoflakes, super architectures expand more active sites and accelerate electron transfer. Moreover, hybridization interaction between Ni 3d, Mo 4d, 4p orbitals leads an asymmetric distribution electric clouds, decreases adsorption energy transformation oxygen‐containing species.

Abstract Rational design of heterostructure catalysts through phase engineering strategy plays a critical role in heightening the electrocatalytic performance catalysts. Herein, novel amorphous/crystalline (a/c) (a‐CoS/Ni 3 S 2 ) is manufactured by facile hydrothermal sulfurization method. Strikingly, interface coupling between amorphous (a‐CoS) and crystalline (Ni a‐CoS/Ni much stronger than that (c‐CoS) crystalline/crystalline (c/c) (c‐CoS/Ni as control sample, which makes meta‐stable structure more stable. Meanwhile, has vacancies (S v c‐CoS/Ni because presence an phase.
