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.

用于增强析氧反应的MoS2量子点修饰NiCo2O4纳米球表面润湿性工程。
调制MoS2量子点可增强NiCo2O4的亲水性,加速气泡脱离,促进传质,从而提高催化活性。优化后的催化剂在10 mA cm-2下的过电位为272 mV,在1.0 mol L-1 KOH下的Tafel斜率为76.3 mV dec1。
