Abstract

We present a fabrication process for hierarchical (Ni,Co)_0.85Se sheets, achieving efficient oxygen evolution reaction (OER) activity with a 10 mA cm^-2 current density at an overpotential of 290 mV. Porous architecture and doping improve kinetics, supported by DFT calculations. This approach offers insights into designing stable, high-performance OER catalysts.
