Efficient photocatalyst for visible light water photolysis DID NOT PRESENT

• In Event: Chemistry & Biochemistry Oral Session 1

Abstract

A visible light active porous metal oxide photocatalyst was prepared using niobium and titanium oxides. The new material exhibits high quantum efficiency in the production of hydrogen from water under visible light, using a sacrificial electron donor. The metal oxide is a wide bad gap semiconductor, which becomes visible light capable when sensitized with a ruthenium based dye. The synthetic methodology introduced creates unique composite materials with outstanding dye loadings. Co-catalysts of metallic nanoparticle platinum are deposited in an unusual way. Synthesis, characterization, and kinetic data will be presented.
