Tungstate Intercalated NiFe Layered Double Hydroxide Enables Long‐Term Alkaline Seawater Oxidation

Small, Journal Year: 2024, Volume and Issue: 20(28)

Published: Feb. 16, 2024

Abstract Renewable electricity‐driven seawater splitting presents a green, effective, and promising strategy for building hydrogen (H 2 )‐based energy systems (e.g., storing wind power as H ), especially in many coastal cities. The abundance of Cl − seawater, however, will cause severe corrosion anode catalyst during the electrolysis, thus affect long‐term stability catalyst. Herein, oxidation performances NiFe layered double hydroxides (LDH), classic oxygen (O ) evolution material, can be boosted by employing tungstate (WO 4 2– intercalated guest. Notably, insertion WO 2− to LDH layers upgrades reaction kinetics selectivity, attaining higher current densities with ≈100% O generation efficiency alkaline seawater. Moreover, after 350 h test at 1000 mA cm −2 , only trace active chlorine detected electrolyte. Additionally, follows lattice mechanism on .
