Jinfa Chang et al.

Summary: Direct seawater electrolysis for hydrogen production is economically appealing yet technically challenging. The iron and phosphor dual-doped nickel selenide nanoporous films were designed as bifunctional catalysts to improve efficiency, selectivity, and stability by enhancing the oxygen evolution reaction selectivity, preventing selenide dissolution, and stimulating active centers for the reaction. The experimental and theoretical analyses provide insights into the roles of dual-dopants in boosting seawater electrolysis, resulting in achieving high current density with OER selectivity and long-term stability.

Efficient overall water splitting catalyzed by robust FeNi3N nanoparticles with hollow interiors

Zong Liu et al.

Summary: The study demonstrated hollow structured FeNi3N nanoparticles with improved intrinsic activity for overall water splitting, achieved through facile oxygen-etching and thermal nitridation. The catalyst showed high catalytic activity, excellent stability, and accelerated catalytic kinetics, with significantly lower overpotentials required for the HER and OER compared to bulk FeNi3N. The enhanced performance was attributed to the metallic characteristic FeNi3N phases, high active site exposure, and boosted intrinsic activity, providing insights for designing transition metal-based catalysts for water electrolysis.
