· Cu1 Hg1 O2

Copper mercury oxide (CuHgO₂) is an experimental semiconductor compound combining copper and mercury oxides, belonging to the family of mixed-metal oxide semiconductors. This material is primarily of research interest for optoelectronic and photocatalytic applications, with potential utility in specialized sensing or catalytic systems where the combined properties of copper and mercury oxides offer advantages over single-component alternatives. However, the material remains largely in the research phase, and toxicity concerns related to mercury content severely limit practical industrial deployment in most applications.
