Electronic structure modulation of Mo sites in anion and cation co-doped MoO2 nanospheres for electrocatalytic water oxidation.

Abstract

Herein, we synthesized a type of anion/cation co-doped MoO2 nanosphere as an efficient OER catalyst. The optimized Ni/N-MoO2 exhibited a lower overpotential of 270 mV at 10 mA cm-2 in 24 h. This work provides a unique direction for the synthesis of efficient and stable MoO2-based electrocatalysts for water splitting.
