Mixed-metal metal-organic frameworks (MMOFs) contain more than one type of metal node, which can improve or even introduce new features compared to the single-metal frameworks. Traditionally, most of the MMOFs are synthesized by solution method which requires all the metal ions to form stable coordination with the ligand in a single framework, and therefore limits the choice of the metal ions. In this work, Pt-doped Zn-MOF-74 (PtZn-MOF-74) has been prepared through a mechanochemical conversion approach from Pt-doped ZnO (Pt-ZnO) directly. The absence of a large quantity of solvent limits the solvation and diffusion of growth species during the mechanochemical conversion and therefore prevented the agglomeration of Pt dopants in PtZn-MOF-74. CO oxidation was used to evaluate the catalytic performance of the prepared MMOFs. Compared with inert Zn-MOF-74, PtZn-MOF-74 with unsaturated coordinated Pt at elevated temperature can act as the active sites to catalyze CO oxidation reaction. This study provides a novel design strategy for the synthesis of MMOFs with extended functionalities. |
