· Co2 Au2 O4

Co₂Au₂O₄ is an experimental mixed-metal oxide semiconductor combining cobalt and gold in an ordered crystal structure. This compound belongs to the family of oxide semiconductors and represents emerging research into noble metal–transition metal oxides for functional electronic and photocatalytic applications. The material is primarily of scientific interest rather than established industrial production, with potential relevance in next-generation optoelectronic devices, photocatalysis, and sensing where the unique electronic properties arising from cobalt–gold interactions could offer advantages over conventional single-metal oxide semiconductors.
