Hydrogen shows great promise as a carbon-neutral energy carrier that can significantly mitigate global challenges, offering sustainable solution. Exploring catalysts are highly efficient, cost-effective, and stable for the hydrogen evolution reaction (HER) holds crucial importance. For this, metal–organic framework (MOF) materials have demonstrated extensive applicability either heterogeneous catalyst or precursor. Herein, nanostructured interface between NiMo/CuO@C derived from Cu-MOF was designed developed on nickel foam (NF) competent HER electrocatalyst in alkaline media. The exhibited low overpotential of 85 mV at 10 mA cm–2 rivals Pt/C (83 @ cm–2). Moreover, catalyst's durability measured through chronopotentiometry constant current density −30, −100, −200 50 h each 1.0 M KOH. Such enhanced electrocatalytic performance could be ascribed to presence conductive C Cu species, facilitated electron transfer components because interface, abundant active sites result multiple oxidation states. existence an ionized oxygen vacancy (Ov) signal confirmed all heat-treated samples paramagnetic resonance (EPR) analysis. This revelation sheds light entrapment electrons various environments, primarily associated with underlying defect structures, particularly vacancies. These trapped play role augmenting conductivity, thereby contributing elevated performance.

The design of non-noble electrocatalysts is the foremost approach to overcome scarcity, and high cost benchmark catalysts applied hydrogen evolution reaction (HER) in alkaline media for green H2 generation. Nevertheless, electroactive arrays based on transition metals with an outstanding faradaic ionic performance HER are unusual, or their electrochemical properties not adequately scrutinized. In this sense, easy two-step route described improve catalytic commercial Ni foam electrodes. As first step, ultrasound-assisted chemical treatment allows obtaining regularly cracked catalysts. Subsequently, surface decorated NiMo-based nanostructures, consequently, active-site density increased, overpotential decreased raised. Regarding last, NiMo80/NiFA reports lowest 18 mV at 4 μA mbar−1, Heyrovsky mechanism as rate-determining step towards HER. differential mass spectrometry (DEMS) employed elucidate onset potential, kinetics, medium.
