Abstract

The study of mixed transition metal oxido cubane complexes is crucial to the development of materials for oxygen evolution reaction, oxygen redn. reaction, and energy storage. A discreet series of heterometallic trimanganese-tetraoxido cubanes (MMn_3O_4 ; M = Fe, Co, Ni, Cu) supported by a trisalkoxy-hexapyridyl ligand with a 1, 3,5-triarylbenzene spacer were synthesized and characterized by single crystal X-ray diffraction, dispersive difference diffraction anal., cyclic voltammetry, Mossbauer spectroscopy, and X-ray absorption spectroscopy. To det. their potential as precursors for heterogeneous water oxidn. electrocatalysts, these well-defined complexes were drop-casted on electrodes, and electrolysis of the material was performed in basic aq. media. Oxygen evolution was obsd., and the activity was compared to a few other mixed metal oxide electrocatalysts reported in literature. Electrolysis of MMn_3O_4 resulted in the different ratio of M to Mn in the final material depending on the metal M (M = Co, Ni) as characterized by XPS and energy dispersive X-ray spectroscopy. X-ray absorption spectroscopy shows the retention of the cubane moiety in the post-electrolysis NiMn_3O_4 materials.
