Outline of Final Research Achievements

We aimed at developing a high-performance heterogeneous catalysts that can be applied to the selective functional group transformations in the liquid phase. High catalytic performance was achieved applying a catalyst design concept using the cooperative action between metal nanoparticles and nanocrystalline metal oxides. Using the various physicochemical characterization, the relationship between the structure of the active sites and activity was estimated. The developed new catalysts were found to be active for the transformation of biomass-derived chemicals including the C-C bond cleavage of primary alcohols, selective hydrogenation of unsaturated compounds such as sugars under mild conditions.
