· CuTaO2S

CuTaO2S is a mixed-metal oxide-sulfide semiconductor compound containing copper, tantalum, oxygen, and sulfur. This is a research-phase material being investigated for photocatalytic and optoelectronic applications, where the combination of transition metals and anionic mixing is intended to engineer electronic band structure and light absorption properties. Its potential lies in photocatalysis for water splitting, environmental remediation, and visible-light-driven reactions—areas where engineers seek alternatives to conventional wide-bandgap semiconductors like TiO2.

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.
