· Co2 Rh4 O8

Co₂Rh₄O₈ is a mixed-metal oxide semiconductor composed of cobalt and rhodium in a spinel-related crystal structure. This is a research-phase material primarily investigated for electrochemical and catalytic applications due to the synergistic properties arising from the combination of transition metals. While not yet widely deployed in commercial products, compounds in this family are of interest for energy conversion, water splitting catalysis, and advanced sensor applications where the dual-metal composition offers improved activity compared to single-metal alternatives.
