氧化铁镍电极上析氧反应的电化学研究
Electrochemical Studies of Iron-doped Nickel Oxide Electrode for Oxygen Evolution Reaction
摘要
Abstract
In this paper, the iron-doped nickel oxide thin film as anode catalyst was prepared by RF reactive sputtering method. The oxygen evolution reaction (OER) on the iron-doped nickel oxide was investigated with cyclic voltammetry, liner sweep voltammetry, polarization curves and electrochemical impedance spectroscopy.Results show that the iron acts as active site in the film which makes the overpotential lower, and changes the rate-limiting from primary discharge of OH - ions to the recombination of oxygen atom. With the increasing of oxygen content in flu ratio during sputtering, the electrocatalytic activities of the film increase. Iron-doped nickel oxide thin film is promising material as OER electrocatalyst for hydrogen production than the nickel electrode.The oxygen overpotential on the film was over 500 mV lower than the overpotential with nickel at 50mA/cm2.关键词
