Synthesis-route-regulated structural and electronic evolution of Fe-doped Co 3 O 4 toward enhanced oxygen evolution reaction
Abstract
. Through a series of characterizations, it was confirmed that, compared to the acidic redox precipitation method, the iron-doped cobalt oxide catalyst prepared by the alkaline chemical precipitation method exhibits superior crystallographic structure. This structure effectively regulates the d-band center position, bringing it closer to the Fermi level, thereby enhancing the adsorption of oxygen-containing intermediates. This adjustment reduces the oxygen evolution reaction energy barrier and optimizes the reaction pathway. The combined optimization of the crystallographic structure and electronic structure significantly improves the electrocatalytic performance of the material and reduces mass transfer resistance during the reaction process.
