Surface wettability engineering of MoS<sub>2</sub> quantum dot-decorated NiCo<sub>2</sub>O<sub>4</sub> nanospheres for enhanced oxygen evolution reaction
Modulating MoS<sub>2</sub> quantum dots enhances the hydrophilicity of NiCo<sub>2</sub>O<sub>4</sub>, 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<sup>-2</sup> and a Tafel slope of 76.3 mV dec<sup>-1</sup> in 1.0 mol L<sup>-1</sup> KOH.
