Ultrathin nanosheets constructed CoMoO4 porous flowers with high activity for electrocatalytic oxygen evolution

Abstract

Hierarchical CoMoO₄ porous micro-flowers assembled from numerous ultrathin nanosheets were synthesized by a facile hydrothermal method. Benefiting from the high specific surface area and constituent nanosheets with an ultrathin thickness, the CoMoO₄ micro-flowers exhibit substantially higher electrocatalytic activity and stability than the IrO₂ benchmark for the oxygen evolution reaction.
