CuTaO2S
semiconductor· 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.
