The efficiency of the fuel cell depends on how well the oxygen reduction reaction (ORR) occurs at the cathode. The solution to making its slow reactions faster is to use effective catalysts. Platinum exhibits the highest activity, and, however, is recommended to reduce its use or replace it with other materials due to its scarcity and high prices. In this study, we tried to develop a non-precious metal catalyst for ORR reaction using MOF (Metal Organic Framework). The structure, morphology, and electrochemical performance of Fe-MOF were examined and the transition metal Ni, which can be expected to improve the catalytic activity, was added to the Fe-MOF synthesis method to confirm the shape and structure. The electrochemical performance of nanosize FeNi-MOF-HT is higher than that of Fe-MOF-HT. Due to the high degree of graphitization and its maintained structure, FeNi-MOF heat-treated at 700 ℃ and 800 ℃ show excellent performance. |
