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.
