La1 Au1 O2

La₁Au₁O₂ is a mixed-metal oxide semiconductor combining lanthanum and gold with oxygen, representing a research-phase compound in the rare-earth metal oxide family. This material is not yet widely commercialized but is studied for its potential electronic and catalytic properties that could arise from the synergistic combination of a rare-earth element with noble metal chemistry. Interest in such compounds typically centers on applications requiring novel optical, electrochemical, or sensing capabilities where the gold component might enhance electron transport or catalytic activity compared to conventional rare-earth oxides alone.
