Fe-Triazole coordination compound-derived Fe₂O₃ nanoparticles anchored on Fe-MOF/N-doped carbon nanosheets for efficient electrocatalytic oxygen evolution reaction

Using FeCl3·6H2O and 1,2,4-triazole (Htrz) as starting materials, an Fe coordination compound (CC), [FeCl3(Htrz)3]·H2O, was synthesized at room temperature. Fe-CC can be partially transformed into an Fe metal-organic framework (MOF), [FeCl2(Htrz)], via low-temperature annealing. After sulfurization at 250, 300, and 400 °C, S-doped Fe2O3/N-doped carbon (denoted as NC)/Fe-MOF, FeS2/NC/Fe-MOF, and FeS2/NC were obtained, respectively. S-doped...
