  • Title: Structural and mechanistic aspects of Mn-oxo and co-based compounds in water oxidation catalysis and potential applications in solar fuel production.

    Journal: J Integr Plant Biol; 2010 Aug; 52(8):704-11. PubMed ID: 20666926.
    Abstract:
    To address the issues of energy crisis and global warming, novel renewable carbon-free or carbon-neutral energy sources must be identified and developed. A deeper understanding of photosynthesis is the key to provide a solid foundation to facilitate this transformation. To mimic the water oxidation of photosystem II oxygen evolving complex, Mn-oxo complexes and Co-phosphate catalytic material were discovered in solar energy storage. Building on these discoveries, recent advances in solar energy conversion showed a compelling working principle by combing the active Mn-oxo and Co-based catalysts in water splitting with semiconductor hetero-nanostructures for effective solar energy harnessing. In this review the appealing systems including Mn-oxo tetramer/Nafion, Mn-oxo dimer/TiO(2), Mn-oxo oligomer/WO(3), Co-Pi/Fe(2)O(3), and Co-Pi/ZnO are summarized and discussed. These accomplishments offer a promising framework and have a profound impact in the field of solar fuel production.
