Outline of Final Research Achievements

The electronic states of Pt or Ni nanoparticles were successfully controlled by a coating of metal-organic framework on the surface of the nanoparticles. In particular, the hydrogen storage properties such as hydrogen capacity were changed after the MOF coating due to the modification of the electronic states. These findings suggest that the presence of a MOF coating has significantly altered the surface/bulk reactivity of the nanocrystals, allowing for more facile reactivity with hydrogen, which we are currently investigating.
