Abstract

original image

Light on the water: The coupling of Raman and EPR spectroscopy was crucial in the study of the activation, operation, and deactivation steps in the light-driven splitting of water catalyzed by iridium and iron. The results may provide the foundation for improved water-reduction catalysts. IrPS=iridium photosensitizer, TEA=triethylamine.
