· Cu3 O2

Cu3O2 is a cuprous oxide-based semiconductor compound that represents an intermediate oxidation state of copper oxides, positioning it between Cu2O and CuO in the copper-oxygen phase diagram. This material is primarily of research interest rather than established industrial use, being investigated for potential applications in photovoltaics, photoelectrochemistry, and optoelectronic devices due to its narrow bandgap and semiconducting properties; it remains largely experimental compared to the more stable and commercially developed Cu2O (cuprous oxide) and CuO (cupric oxide) alternatives.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
