Аннотация

Investigations of the effects of the support on catalytic properties are important for heterogeneous systems. Herein, we report the preparation of highly dispersed Pt nanoparticles (NPs) in three isomorphous UiO‐67‐type metal–organic frameworks (MOFs), namely, pristine UiO‐67, N‐UiO‐67, and NH 2 ‐UiO‐67. Structural measurements revealed that the sizes of the Pt NPs were 4.5 nm for Pt/UiO‐67 and 2.5 nm for N‐UiO‐67 and NH 2 ‐UiO‐67. The dominant influences on the sizes of the Pt NPs are the functional groups of the support and the pore size of the MOF. Furthermore, CO catalytic oxidations were performed as a model reaction. Interestingly, the catalytic performance sequence is 5 % Pt/N‐UiO‐67 > 5 % Pt/UiO‐67 > 5 % Pt/NH 2 ‐UiO‐67. A combination of experimental measurement and DFT calculation revealed that the catalytic properties depend on not only the size of the Pt NPs but also the nature of the support.
