- MANUFACTURING METHOD OF WATER SPLITTING ELECTRODE BASED ON FE-NI ALLOY BY ANODIZATION AND WATER SPLITTING ELECTRODE MANUFACTURED THEREBY

摘要

Provided is an oxygen generating catalytic electrode for water splitting, comprising the step 1 of performing anodization of the surface of an iron (Fe)-nickel (Ni) alloy with the current density of 0.05 to 1 mA/cm^2, and forming Fe-Ni hydroxide layers. According to one aspect of the present invention, the specific surface area of the Fe-Ni alloy film can be increased through anodization for a short period of time at a low temperature and excellent overvoltage can be expressed when using the Fe-Ni alloy film as a catalytic electrode for water splitting.
