Abstract

In this study, copper selenium nanostructures (Cu₂Se Ns) were successfully grown and integrated onto a nanoneedle like structured oxidized copper (Cu) mesh via a simple hydrothermal approach. The nanoneedles were formed on the Cu mesh annealing at 400 °C in an air atmosphere. The Cu₂Se electrocatalyst exhibited excellent oxygen evolution reaction (OER) activity, with a low overpotential, enhanced charge transfer kinetics, and long-term operational stability.
