본 발명은 선박평형수를 살균 처리하기 위한 선박평형수 전기분해용 전극에 있어서, 메탈 메쉬, 메탈 폼 및 메탈 플레이트에서 선택된 하나 이상을 포함하고, 이들 상부에는 Pt, Ru 및 Ti 촉매층이 위치하며, 상기 촉매층은 Ru, Ti, 및 Pt으로 구성된 3원계 화합물이고, 상기 촉매층에서 Pt:Ru의 몰비는 2:8 내지 8:2이고, Ti 혼합 후 (Pt : Ru)와 Ti의 몰비는 1:1 내지 3:7이며, 상기 전기분해용 전극에 로딩된 Pt, Ru 및 Ti 촉매량은 0.5 내지 5 mg/cm2을 포함하는 선박평형수 전기분해용 전극에 관한 것이다.본 발명에 따른 선박평형수 전기분해용 전극은 물 산화와의 경쟁에도 염소산화 효율이 저하되지 않고 활성염소종 생성에 대해 98% 이상의 선택성을 보인다. 또한, 귀금속의 함량을 줄여 촉매층을 제조하므로 촉매의 경제성을 확보할 수 있는 장점이 있다.

    The present invention relates to an electrode for electrolyzing ballast water to sterilize ballast water, the electrode comprising at least one selected from a metal mesh, a metal foam, and a metal plate and having a Pt, Ru, and Ti catalyst layer disposed thereon, wherein the catalyst layer ranges in the combination molar ratio of Pt: Ru from 1:9 to 9:1 and in the molar ratio of (Pt:Ru):Ti from 1:1 to 3, and the amount of the Pt, RU, and Ti catalyst loaded into the electrode for electrolysis is 0.5 to 5 mg/cm2. The electrode for ballast water electrolysis according to the present invention does not decrease chlorine oxidation efficiency even in competition with water oxidation and shows a selectivity of 98% or more for generation of active chlorine species. In addition, since the catalyst layer is prepared with a reduced content of precious metals, there is an advantage in securing economic feasibility of the catalyst.
