Reversible visible-light photooxidation of an oxomanganese water-oxidation catalyst covalently anchored to TiO2 nanoparticles.
Several polynuclear transition-metal complexes, including our own dinuclear di-μ-oxo manganese compound [H(2)O(terpy)Mn(III)(μ-O)(2)Mn(IV)(terpy)H(2)O](NO(3))(3) (1, terpy = 2,2':6',2''-terpyridine), have been reported to be homogeneous catalysts for water oxidation. This paper reports the covalent attachment of 1 onto nanoparticulate TiO(2) surfaces using a robust chromophoric linker L. L, a p...
متن کاملSurface Structure of TiO2 Rutile (011) Exposed to Liquid Water
The rutile TiO2(011) surface exhibits a (2 × 1) reconstruction when prepared by standard techniques in ultrahigh vacuum (UHV). Here we report that a restructuring occurs upon exposing the surface to liquid water at room temperature. The experiment was performed in a dedicated UHV system, equipped for direct and clean transfer of samples between UHV and liquid environment. After exposure to liqu...

Nanostructured MnO(2) exhibits a high turnover frequency for oxygen evolution under visible light and high stability in strong acidic conditions.
متن کاملNonstoichiometric rutile TiO2 photoelectrodes for improved photoelectrochemical water splitting.
A new type of nonstoichiometric rutile titanium dioxide (TiO2) film with around 15 at% oxygen vacancies homogeneously distributed throughout the bulk was prepared. The resultant films, when used as a photoelectrode, showed a photoelectrochemical water splitting activity 1.7 times that of stoichiometric TiO2 at a bias of 0.9 V vs. Ag/AgCl. This is believed to result from the synergistic effect o...
