semiconductor

· Zn4 Co2 Ir2 O12

Zn₄Co₂Ir₂O₁₂ is a mixed-metal oxide semiconductor composed of zinc, cobalt, and iridium in a pyrochlore or spinel-related crystal structure. This is a research-phase compound of interest for electrochemistry and catalysis due to the synergistic properties of transition metals (Co, Ir) combined with the base-metal stability of zinc oxide. Unlike simpler binary oxides, this quaternary composition offers tunable electronic and catalytic properties for energy conversion and electrocatalytic applications, though industrial deployment remains limited and material development is ongoing.
