The Photolysis of Bis(cyclopentadienyl)molybdenum Oxide in Water. The Catalytic Production of Hydrogen.
Abstract
Photocatalytic production of hydrogen from water has been a long term goal of inorganic photochemistry. Previous research efforts can be summarized in terms of four methods that will decompose water in hydrogen and oxygen. They include the use of simple metal salts, metal complexes, intermolecular electron transfer with sensitizers, and photoelectrochemical methods. Early studies centered around intermolecular electron transfer with sensitizers although catalytic cycles were difficult to complete because sacrificial agents had to be used to maintain the reaction. The recent application of photoelectrochemical methods offers considerable promise, especially with photosensitive dye containing cells. Complementary use of metal complexes, however, appears to be particularly effective for two reasons: (a) many metal complexes can photocatalyze the decomposition of water; and (b) ligand design offers the potential of modifying metal complexes to achieve catalysis. Nevertheless there are few well characterized metal complexes that will photochemically produce hydrogen from water. We report here the photocatalytic synthesis of hydrogen and peroxide from water by bis(cyclopentadienyl)molybdenum oxide.
