摘要： The present invention relates to an anode for electrolysis having reduced overvoltage and improved lifetime while exhibiting high efficiency and a method of preparing the same. Since the anode for electrolysis according to the present invention is prepared by electrostatic spray deposition, an active material may be uniformly distributed in a catalyst layer, and thus, an overvoltage may be reduced and lifetime may be improved while exhibiting high efficiency.
