Hierarchical (Ni,Co)0.85Se Sheets for Efficient Oxygen Evolution Reaction Electrocatalysis: A Combined Approach of Fabrication Control and Mechanistic Understanding
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.
