Abstract

Modulating MoS₂ quantum dots enhances the hydrophilicity of NiCo₂O₄, accelerates bubble detachment, promotes mass transfer, and consequently enhances catalytic activity. The optimized catalyst achieves a low overpotential of 272 mV at 10 mA cm⁻² and a Tafel slope of 76.3 mV dec⁻¹ in 1.0 mol L⁻¹ KOH.
