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 Carbon‐based nanomaterials play a significant role in the field of electrochemistry because their outstanding electrical conductivity, chemical and thermal resistance, structural flexibility, so on. In recent years, we have observed rapid rise research interest high‐temperature shock (HTS) method, which is fast, stable, environmentally friendly, versatile. The HTS method offers excellent controllability repeatability while tackling challenges limitations traditional preparation methods, providing new way to prepare optimize carbon‐based for electrochemical applications. During synthesis, reaction driven by high temperature further growth obtained nanoparticles inhibited heating cooling rates. has many advantages, including controlled carbon vacancy that may drive phase transformation, precise engineering carbon, other defects function as active centers, formation preservation metastable owing energy cooling, fine‐tuning interaction between loaded species support optimized performance, facile doping compounding induce synergy different constituents. This article provides comprehensive review various prepared applications during past decade, emphasizing synthesis principles performance. Studies showcasing merits HTS‐derived advancing Lithium‐ion batteries, Lithium‐sulfur Lithium‐air water‐splitting reaction, oxygen reduction CO 2 nitrate electrocatalytic reactions, fuel cells are highlighted. Finally, prospects recommended.

Abstract Electrochemical nitrate reduction to ammonia (NRA) is a promising approach for alleviating energy crisis and water pollution. Current NRA catalysts are challenged simultaneously improve the rate of adsorption desorption processes further increase total activity due Brønsted−Evans−Polanyi (BEP) relationships. Herein, two‐step Joule heating method utilized preparation Ni 0.25 Cu 0.5 Sn nanometallic glass containing synergistic catalytic sites enhance processes. Kelvin probe force microscopy reveals pronounced oscillatory behavior in surface potential glass, which an important feature site, empirical formula proposed quantitatively characterize its characteristic. In situ electrochemical Raman spectroscopy indicates promotion nickel tin atoms processes, respectively. DFT calculations demonstrated that presents wide range distributions favor multisite catalysis. The present work provides new ideas design understanding highly active catalysts.
