It is not enough to develop an ideal hydrogen evolution reaction (HER) electrocatalysts by single strategy. Here, the HER performances are significantly improved combined strategies of P and Se binary vacancies heterostructure engineering, which rarely explored remain unclear. As a result, overpotentials MoP/MoSe2 -H heterostructures rich in 47 110 mV at 10 mA cm-2 1 m KOH 0.5 H2 SO4 electrolytes, respectively. Especially, KOH, overpotential very close commercial Pt/C beginning even better than when current density over 70 . The strong interactions between MoSe2 MoP facilitate electrons transfer from Se. Thus, possesses more electrochemically active sites faster charge capability, all favor high activities. Additionally, Zn-H2 O battery with as cathode fabricated for simultaneous generation electricity, displays maximum power up 28.1 mW stable discharging performance 125 h. Overall, this work validates vigorous strategy provides guidance development efficient electrocatalysts.

Developing highly active and robust electrocatalysts for the hydrogen/oxygen evolution reaction (HER/OER) is crucial large-scale utilization of green hydrogen. In this study, a collaborative interface optimization guided strategy was employed to prepare metal-organic framework (MOF) derived heterostructure electrocatalyst (MXene@RuCo NPs). The obtained requires overpotentials only 20 mV HER 253 OER deliver current density 10 mA/cm2 in alkaline media, respectively, it also exhibits great performance at high density. Experiments theoretical calculations reveal that doped Ru introduces second sites decreases diameter nanoparticles, which greatly enhances number sites. More importantly, MXene/RuCo NPs heterogeneous interfaces catalysts exhibit synergistic effects, decreasing work function catalyst improving charge transfer rate, thus reducing energy barrier catalytic reaction. This represents promising development MOF-derived achieve efficient conversion industrial applications.
