Urea-assisted electrolytic water splitting is recognized as a high-efficiency and energy-saving hydrogen production technology because of its advantages reducing the thermodynamic electrode potential decomposing pollutant. Furthermore, reasonably designed heterojunction catalyst can significantly accelerate kinetic rate urea oxidation reaction (UOR). In this paper, four-component (including NiCo, NiCoP, Ni3Se2, NiSe) NiCo-based heterostructure (expressed NixSey/NC-NCP) was successfully synthesized by combining electrodeposition method high-temperature selenization strategy, which consists an interlaced chainlike structure interconnected nanosphere structure. As expected, NixSey/NC-NCP only requires low 1.36 V to enable UOR deliver current density 100 mA cm–2, 208 mV lower than that corresponding oxygen evolution (OER). The results physical characterizations confirm surface reconstructed during electrocatalytic process; is, active species such CoOOH NiOOH were generated on surface. Pt/C||NixSey/NC-NCP electrolyzer composed commercial Pt/C self-supporting used for urea-assisted splitting, needs cell voltages 1.40 1.45 drive densities 200 respectively. This study promotes research hierarchical catalysts enhance performance, effectively energy required electrochemical production.

Constructing transition metal multiphase composites can improve the electrocatalytic efficiency of (sea)water splitting via interfacial interaction between adjacent active sites. Herein, self-supporting NimSn-FeOx heterostructure is in situ grown on nickel foam (NF) through a corrosion engineering approach, which displays abundant dendritic array structures, endowing material with sites and high area. The control introducing Fe3+ sulfur precursors effectively trigger phase transiting from Ni3S2 to Ni9S8, generating more S vacancies, could reduce reaction energy barrier performance. Simultaneously, presence Fe–S bonding at sulfide/oxide interface brings strong electronic interaction, enables tuning adsorption intermediates accelerates catalytic kinetics. As result, Ni9S8–FeOx/NF-Fe8.0 catalyst presents low overpotentials 159 mV 190 for oxygen evolution 100 mA cm–2 under 1 M KOH solution simulated seawater conditions, respectively. overall water incorporating as both anode cathode provides potential 1.707 V 1.794 cm–2. This research furnishes an efficient strategy toward design advanced heterogeneous splitting.
