Synthesis of Oxygen Evolution Reaction Electrocatalysts by Element Dissolution in Alkaline Earth Metal Iridates

摘要

Embodiments of the present invention provide a catalyst comprising an alkaline earth metal based on iridium. At this time, the alkaline earth metal is dissolved according to the electrochemical reaction, which leads to an increase in the catalyst surface area and an increase in activity. It is significant that the catalyst activity was increased by using the element dissolution phenomenon in the acid electrolyte, which previously lowered the catalyst stability, and that the element dissolution phenomenon was directly observed.
