Abstract

A novel three-dimensional (3D) superstructure of cobalt hydroxide carbonate assembled from nanoneedles has been synthesized via a facile hydrothermal method. Furthermore, we tested the electrocatalytic oxygen evolution reaction performance, which demonstrated that the superstructure exhibited high catalytic activity, achieving 10 mA cm-2 at a low overpotential of merely 240 mV.
