Abstract The state-of-the-art anion-exchange membrane water electrolyzers (AEMWEs) require highly stable electrodes for prolonged operation. stability of the electrode is closely linked to effective evacuation H 2 or O gas generated from surface during electrolysis. In this study, we prepared a super-hydrophilic by depositing porous nickel–iron nanoparticles on annealed TiO nanotubes (NiFe/ATNT) rapid outgassing such nonpolar gases. NiFe/ATNT exhibited an overpotential 235 mV at 10 mA cm −2 oxygen evolution reaction in 1.0 M KOH solution, and was utilized as anode AEMWE achieve current density 1.67 A 1.80 V. addition, with electrode, which enables outgassing, showed record 1500 h 0.50 under harsh temperature conditions 80 ± 3 °C.

A deep eutectic solvent (DES) was prepared by mixing tetraalkylphosphonium chloride ([P 4444 ]Cl) and glycerol in a 1:2 molar ratio. Nickel nitrate dissolved this DES, then the mixture heated at 350 °C to obtain phosphorus‐doped nickel catalysts. In system, DES plays multiple crucial roles. (1) It serves as reaction medium, providing suitable environment for synthesis of Ni‐based (2) actively participates catalyst preparation reactant. [P ]Cl acts P source, while effectively promotes formation metal reducing agent. (3) exhibits templating effect, inducing morphology product be unique thin sheet with angular edges. The synthesized P‐doped Ni material excellent hydrogen evolution performance water splitting. an acidic environment, when current densities reached 10 20 mA cm −2 , overpotentials were only 90.2 115.9 mV, Tafel slope low 55.6 mV dec −1 . alkaline also performed well. η values 107.0 145.4 respectively. 57.0
