Direct seawater electrolysis is promising for sustainable hydrogen gas (H2) production. However, the chloride ions in lead to side reactions and corrosion, which result a low efficiency poor stability of electrocatalyst hinder use technology. Here we report corrosion-resistant RuMoNi electrocatalyst, situ-formed molybdate on its surface repel ions. The works stably over 3000 h at high current density 500 mA cm-2 alkaline electrolytes. Using catalyst an anion exchange membrane electrolyzer,...
Constructing stable electrodes which function over long timescales at large current density is essential for the industrial realization and implementation of water electrolysis. However, rapid gas bubble detachment usually results in peeling-off electrocatalysts performance degradation, especially term operations. Here we construct a mechanically-stable, all-metal, highly active CuMo6S8/Cu electrode by in-situ reaction between MoS2 Cu. The Chevrel phase exhibits strong binding...
Abstract Production of green hydrogen (H 2 ) by water electrolysis is important for achieving the global mission carbon neutrality. For this, acidic with a higher current density operation and energy conversion efficiency compared alkaline has attracted much attention. The four‐electron‐transfer oxygen evolution reaction (OER) limits overall devices. In recent years, low‐dimensional OER catalysts have been extensively explored to increase such devices, but most them work well only at low...

Main group indium materials have been known as promising electrocatalysts for two-electron-involved carbon dioxide reduction to produce formate, which is a key energy vector in many industrial reactions. However, the synthesis of two-dimensional (2D) monometallic nonlayered remains great challenge. Here, we present facile electrochemical strategy transform 2D coordination polymer into elemental nanosheets. In customized flow cell, reconstructed metallic exhibits high Faradaic efficiency (FE)...
Abstract The carbon dioxide reduction reaction (CO 2 RR) driven by electricity can transform CO into high‐value multi‐carbon (C 2+ ) products. Copper (Cu)‐based catalysts are efficient but suffer from low C selectivity at high current densities. Here La(OH) 3 in Cu catalyst is introduced to modify its electronic structure towards RR products ampere‐level /Cu has a remarkable Faradaic efficiency (FE C2+ of 71.2% which 2.2 times that the pure density 1,000 mA cm −2 and keeps stable for 8 h. In...
The simulation of a two-phase acidizing process coupled with thermal–chemical–fracturing is complex task, given the presence natural fractures in carbonate rocks and influence temperature on acid–rock reaction. In this work, we introduce mixed computational strategy combining operator splitting Newton iteration built upon embedded discrete fracture model. This innovative designed to tackle nonlinear problems arising from coupling multiphysics fields. porosity improved region within rock...
As one of the best electrocatalysts for hydrogen evolution reaction, platinum catalysts are a benchmark performance evaluation new catalysts. However, reported in literature show diverse electrocatalytic performances, resulting lack common reference standard. In this study, we investigated several factors that affect by performing experimental measurements and data processing. These included solution resistance, electrolyte temperature, loading quantity, catalyst microstructure,...
The electrochemical reduction of CO2 to CH4 is promising for carbon neutrality and renewable energy storage but confronts low selectivity, especially at high current densities. key challenge lies in promoting *CO intermediate *H coupling while minimizing side reactions including C‐C or H‐H coupling, which particularly difficult density due abundant intermediates.
