Oxygen-vacancy-mediated electron localization at the nickel sites in nickel/iron layered double hydroxide towards efficient oxygen evolution reaction

“…Transition metals can be strategically structured into a series of metal complexes, such as oxides (hydroxides), 3 sulfides, 4 phosphides, 5 and nitrides 6 for OER electrocatalytic reactions. Among various materials, the remarkable attributes of transition-metal layered double hydroxides (LDHs), such as their abundance in nature, compositional flexibility, and straightforward synthesis processes, have engendered significant research interest.…”

Nanoporous Nickel Cathode with an Electrostatic Chlorine-Resistant Surface for Industrial Seawater Electrolysis Hydrogen Production

“…In principle, the most promising strategy to improve the electrolytic performance of Ni cathodes is to simultaneously regulate the nanostructure and electronic structure of metallic Ni. − Various Ni-based composite electrodes such as NiPt, NiMo, and NiW have been developed to regulate the electronic structure and improve the intrinsic activity of Ni electrodes. − Strategies to control the nanostructure of Ni electrodes include assembling Ni particles on carbon nanotubes to construct one-dimensional structures or preparing Ni­(OH) 2 nanosheets to build two-dimensional structures. − Unfortunately, many of these methods involve expensive raw materials (such as noble metal Pt and carbon nanotubes or complex synthesis procedures such as a five-step calcination and a microwave method), limiting their suitability for large-scale applications. More importantly, there has been rare consideration on the chlorine-resistant performance of Ni-based cathodes, leading to their high electrolytic performance in fresh water but not in seawater, let alone under industrial current density (0.4–1 A cm –2 ) conditions .…”
