Abstract Rational design of heterostructure catalysts through phase engineering strategy plays a critical role in heightening the electrocatalytic performance catalysts. Herein, novel amorphous/crystalline (a/c) (a‐CoS/Ni 3 S 2 ) is manufactured by facile hydrothermal sulfurization method. Strikingly, interface coupling between amorphous (a‐CoS) and crystalline (Ni a‐CoS/Ni much stronger than that (c‐CoS) crystalline/crystalline (c/c) (c‐CoS/Ni as control sample, which makes meta‐stable structure more stable. Meanwhile, has vacancies (S v c‐CoS/Ni because presence an phase. Eventually, for oxygen evolution reaction (OER), exhibits significantly lower overpotential 192 mV at 10 mA cm −2 compared to (242 mV).

Electrochemical water splitting prompted by organic molecules presents a competitive prospect for implementing energy-efficient hydrogen evolution and alleviating organic-rich pollution. In this work, we fabricated heterojunction of CoFe-layered double hydroxide (CoFe LDH) needles on MoS2/Ni3S2/nickel foam (NF) nanoarrays LDH/MoS2/Ni3S2/NF) forming Schottky interface p–p interface.

Exploring highly effective bifunctional electrocatalysts with surface structural advantages and synergistic optimization effects among multimetals is greatly important for overall water splitting. Herein, we successfully synthesized Pt-loaded NiFe-metal-organic framework nanosheet arrays grown on nickel foam (Pt–NiFe-MOF/NF) via a facile hydrothermal-electrodeposition process. Benefiting from large exposed specific surface, optimal electrical conductivity efficient metal-support interaction endow Pt–NiFe-MOF/NF catalytic performance, exhibiting small overpotential of 261 mV toward oxygen evolution reaction 125 hydrogen at current density 100 mA cm–2 in alkaline medium. More significantly, the assembled electrolyzer comprising Pt–NiFe-MOF/NF//Pt–NiFe-MOF/NF couple demands low cell voltage 1.45 V to reach 10 cm–2. This work renders viable approach design dual-functional exceptional electrocatalytic activity stability high density, showing great prospect electrolysis commercial application.
