Photosensitization of CuI – the role of visible light induced CuI → CuII transition in photocatalytic degradation of organic pollutants and inactivation of microorganisms

Modification of copper iodide with [Cu(SCN)₂(phen)₂] leads to its photosensitization due to the metal to metal (Cu^I → Cu^II) charge transfer transition. The Cu^II-modified Cu^I shows an enhanced visible light induced photoactivity.

Nanostructured charge transfer complex of CuTCNQF4 for efficient photo-removal of hexavalent chromium
