In this study, iron-nitrogen-carbon (Fe-N-C) catalyst samples were prepared by the method of pyrolysis of metal-organic framework materials. Firstly, 2-methylimidazole, Zn(NO3)26H2O, and Fe(NO3)39H2O were dissolved in methanol and ultrasonically dispersed, then the mixed solution was transferred to a reaction vessel and heated at 130°C for 4h. The heated material was washed three times with DMF and twice with methanol and dried overnight at 80°C under vacuum to obtain the precursor Fe-ZIF-8. Next, the precursor precipitate was dried and grounded into a powder form. Finally, the powder was calcined at 850°C in a flowing nitrogen atmosphere for 2 hours, then cooled to room temperature after calcination to obtain the catalyst sample.
