Zusammenfassung:The present invention relates to an electrode for electrolysis and a manufacturing method thereof. The electrode for electrolysis of the present invention has a needle-like structure of a rare earth metal that is further developed than an existing electrode, and thus the fall of a catalyst material is suppressed, thereby exhibiting excellent durability such as stable performance even under reverse current. In addition, the electrode for electrolysis of the present invention has a low overvoltage value, which can significantly reduce the overvoltage demand of an electrolytic cell. Further, according to the method for manufacturing an electrode for electrolysis of the present invention, the electrode for electrolysis having the effect described above can be manufactured without introducing an additional precursor or changing a manufacturing facility. 본 발명은 전해용 전극 및 이의 제조방법에 관한 것이다. 본 발명의 전해용 전극은 기존 전극에 비하여 희토류 금속의 침상 구조가 발달되어 있어 촉매 물질의 탈락이 억제되며, 이에 따라 역전류 시에도 안정된 성능을 나타내는 등 내구성이 우수하다. 또한 본 발명의 전해용 전극은 과전압 수치가 낮아 전해 셀의 과전압 요구량을 현저히 감소시킬 수 있다. 또한, 본 발명의 전해용 전극의 제조방법에 따르면 추가 전구체의 도입이나 제조 설비의 변경 없이도 상기 효과를 갖는 전해용 전극을 제조할 수 있다.
