      内容

      image

      We apply state-of-the-art scanning probe microscopy techniques to study single-atom catalysis. We try to clarify fundamental properties of transition metals dispersed on oxide supports and to understand how the interaction with the substate modify their reactivity with different molecular species for hydrogen production and other energy sources.
      We also simultaneously combine scanning tunneling microscopy and atomic force microscopy to study chemical reactions of organic molecules at surfaces.

      まとめ

      Our research approach bears potential to find combinations of materials for enhancing the production of hydrogen and methanol, as well as to find novel approaches to produce chemical reactions of organic compounds that only occur in the presence of the reactants at surfaces.
