Visible-Light-Driven H2 Generation from Water and CO2 Conversion by Using a Zwitterionic Cyclometalated Iridium(III) Complex

Visible-Light-Driven H2 Generation from Water and CO2 Conversion by Using a Zwitterionic Cyclometalated Iridium(III) Complex:

From light comes hydrogen: Photosensitizer [Ir(4-CF₃bt)₂(Hbpdc)] behaves as a very active promoter towards H₂ evolution from water when irradiated with visible light (see figure). A remarkable selective-photoreduction for CO₂ was also achieved.
