Refers to a heterolaminar film made up of multi-layer compositions, with multiple metal complexes in the form of pillars arranged on a support substrate, the pillars comprising divalent portions of electron acceptor, with a phosphonate or arsenate at each end. Each layer of parallel abutments is separated by a layer of a group metal (IVA), (IVB =, (IIA) or (IIIB), or a tanthanide. The compositions may further comprise particles of at least one Group VIII metal at zero valence trapped within each stratum of the complex. The complexes can also incorporate stalactites and stalagmites of arsenate or phosphonate protected binders, interspersed with the pillars, which provide a series of interstices around each electron acceptor group. be composed of an organic polymer template.The complexes are useful for the conversion and storage of solar energy, for the production of photoelectric currents and as catalysts in reduction reactions, for example, the production of hydrogen peroxide from oxygen gasees and hydrogen, the production of H2 gas from water and the reduction of ketones to form alcohols. |
