abstract = {Using powder-based ink appears to be the most suitable
candidate for commercializing the membrane electrode
assembly (MEA), while research on the powder-based NPM
catalyst for anion exchange membrane water electrolyzer
(AEMWE) is currently insufficient, especially at high
current density. Herein, a sulfur source (NiFe Layered
double hydroxide adsorbed) confinement strategy is developed
to integrate Ni3S2 onto the surface of amorphous/crystalline
NiFe alloy nanoparticles (denoted NiFe/Ni-S), achieving
advanced control over the sulfidation process for the
formation of metal sulfides. The constructed interface under
the sulfur source confinement strategy generates abundant
active sites that increase electron transport at the
electrode-electrolyte interface and improve ability over an
extended period at a high current density. Consequently, the
constructed NiFe/Ni-S delivers an ultra-low overpotential of
239 mV at 10 mA cm−2 and 0.66 mAunder an overpotential of
300 mV. The AEMWE with NiFe/Ni-S anode exhibits a cell
voltage of 1.664 V @ 0.5 A cm−2 and a 400 h stability at
1.0 A cm−2.},
