Abstract

금속 산화물 나노선을 함유하는 혼합 촉매 제조방법, 이에 의해 제조된 혼합 촉매를 포함하는 전극 및 연료전지를 제공한다. 혼합 촉매 제조방법은 제1 금속 전구체와 제2 금속 전구체가 함유된 고분자 용액을 전기방사하여 금속-고분자 혼합 나노선을 형성하는 단계, 금속-고분자 혼합 나노선을 열처리하여 금속 산화물 나노선을 형성하는 단계 및 금속 산화물 나노선과 활성금속 나노입자를 혼합하는 단계를 포함한다. 여기서, 상기 제2 금속 전구체의 금속은 상기 금속 산화물 나노선의 도펀트로 사용된다. 제조된 혼합 촉매를 사용하여 연료전지의 전극 촉매층을 구성하는 경우 연료전지의 성능을 크게 향상시킬 수 있으며, 발전단가를 낮출 수 있는 장점이 있다.
