A collaborative investigation of the fundamental aspects of hydrogen production by photocatalytic water-splitting based on oxomanganese-functionalized TiO2 nanoparticles is presented. Among the very few active non-biological catalysts, these robust and inexpensive high-valent oxomanganese complexes are known to be effective catalysts for water-oxidation in homogeneous solution, but have not previously been coupled to a photo-driven oxidant. By efficiently coupling these catalyst's oxygen-evolution at a photoanode to an energy source (e.g., solar light) and an electron sink (e.g., a counter-electrode where electrons are collected through hydrogen evolution), this scheme represents a significant departure from previous efforts in heterogeneous photocatalysis, and offers the opportunity to address structure/function relations critical to achieving the necessary efficiency breakthroughs that will make photoelectrochemical water oxidation an economically viable solar fuel resource. This is an abstract of a paper presented at the AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
