Abstract

Of noble descent: A fully noble-metal-free system for the photocatalytic reduction of water at room temperature has been developed. This system consists of CuI complexes as photosensitizers and [Fe3(CO)12] as the water-reduction catalyst. The novel Cu-based photosensitizers are relatively inexpensive, readily available from commercial sources, and stable to ambient conditions, thus making them an attractive alternative to the widely used noble-metal based systems.
