Abstract :

There are three possibilities: Homogeneous catalysis using dyads or triads and also intermolecular approaches. Nearly homogeneous systems containing quantum dots or nanomaterials as WRC (water reduction catalyst). Truely heterogeneous systems consisting of suspensions of inorganic particles. Interestingly triadic systems containing noble metals are suitable as model systems: single crystal X-ray structure of a typical supramolecular triad A-L-C consisting of a visible light absorber (A), a tetraphosphane as bridging ligand (L), and a water reduction catalyst (C). This is a homogeneous, molecular approach. Though it has been known for some time that colloidal palladium catalyzes the photochemical water splitting reaction, a new type of nanomaterial consisting of 2.0 nanometer sized particles was developed. Photocatalytic hydrogen production of the semiconductor Ga2B3O7(OH) in methanol/water has been achieved only recently.
