摘要
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。
Surface wettability engineering of MoS2 quantum dot-decorated NiCo2O4 nanospheres for enhanced oxygen evolution reaction†
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.
