| Outline of Final Research Achievements |
Major objective of this study is to develop a preparation method for zeolite-coating metal nanoparticle with bird-cage structure. Rhodium-complex nanoparticles were first prepared in micro-emulsion solution, followed by formation of MFI zeolite layer on the complex nanoparticles. TEM observation and H2-pulse methods, it was revealed that Rh nanoparticles with the size of approximately 3 nm were completely coated with MFI zeolite (Rh@MFI bird-cage material). Moreover, the Rh nanoparticle in the bird-cage material possessed strong resistance to sintering at high temperature (500～700℃). Because Rh inside the MFI zeolite are oxidized and reduced, a molecule can reach the Rh nanoparticles immobilized inside the MFI zeolite. Finally, MFI zeolite-coating Pt nanoparticle with bird-cage structure was successfully prepared by the same experimental procedure.
