Optimizing the electronic structure lies at the core of promoting the intrinsic activity of electrocatalyst for oxygen evolution reaction (OER). Herein, we incorporated Mo dopants and Ni vacancies into two-dimensional ultrathin NiOOH to boost the OER activity. Experimental results exhibited that the integration of two defects modulate the electronic structure and generate more high-valance Ni species under OER conditions, which greatly enhance the catalytic performance by delivering a high current density of 30 mA cm-2 at a low overpotential of 280 mV. Density functional theory calculations id...
