Amorphous FeCoNiBOx nanosheets as highly active and durable electrocatalysts for oxygen evolution reaction in alkaline electrolyte†
Abstract
An amorphous FeCoNiBOx catalyst is fabricated through low-temperature chemical-reduction, and exhibits remarkable oxygen evolution reaction (OER) electrocatalytic properties due to the synergistic effects of multiple elements, amorphous nanostructure, and in situ reconstructed surface with high activity triggered by borate leaching, which improves the electronic conductivity and provides abundant accessible active sites for OER.
