    Sammanfattning : Photoinduced electron transfer is involved in a number of photochemical and photobiological processes. One example of this is photosynthesis, where the absorption of sunlight leads to the formation of charge-separated states by electron transfer. LÄS MER

  3. 3. Molecular Approaches to Photochemical Solar Energy Conversion Towards Synthetic Catalysts for Water Oxidation and Proton Reduction

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Gerriet Eilers; Uppsala universitet.; [2007]
    Nyckelord :Physical chemistry; artificial photosynthesis; solar fuel; WOC; OEC; accumulative electron transfer; hydrogenase mimic; oxygen evolution; proton reduction; water oxidation; Fysikalisk kemi;

    Sammanfattning : A molecular system capable of photoinduced water splitting is an attractive approach to solar energy conversion. This thesis deals with the functional characterization of molecular building blocks for the three principal functions of such a molecular system: Photoinduced accumulative charge separation, catalytic water oxidation, and catalytic proton reduction.
