The present invention relates to a non-platinum catalyst for an oxygen reduction electrode, in which iron nanoparticles are dispersed in nitrogen-doped mesoporous carbon nanofibers, and the surfaces of the iron nanoparticles are at least partially exposed to the outside. In addition, the present invention relates to a method for producing a non-platinum catalyst for an oxygen reduction electrode using electrospinning and hydrogen activation reactions. La présente invention se rapporte à un catalyseur ne contenant pas de platine pour une électrode de réduction de l'oxygène, des nanoparticules de fer étant dispersées dans des nanofibres de carbone mésoporeuses dopées à l'azote et les surfaces des nanoparticules de fer étant au moins partiellement exposées à l'extérieur. De plus, la présente invention se rapporte à un procédé permettant de produire un catalyseur ne contenant pas de platine pour une électrode de réduction de l'oxygène utilisant l'électrofilature et des réactions d'activation de l'hydrogène. 본 발명은 산소환원 전극용 비백금계 촉매에 관한 것으로, 질소 도핑된 메조다공성 탄소나노섬유 내부에 철 나노입자가 분산되어 있되, 상기 철 나노입자의 적어도 일부의 표면이 외부로 노출되어 있는 것을 특징으로 한다. 또한, 본 발명은 전기방사 및 수소 활성화 반응을 이용하여 산소환원 전극용 비백금계 촉매를 제조하는 방법에 관한 것이다.
