Regulating the size and spatial distribution of Pd nanoparticles supported by the defect engineered metal–organic framework HKUST-1 and applied in the aerobic oxidation of cinnamyl alcohol

摘要: The functional composite of metal nanoparticles (NPs) and defect-engineered metal–organic frameworks (DE-MOFs), NPs@DE-MOFs, is an emerging field MOF materials chemistry. Herein, we report on a series novel Pd-NPs@DE-HKUST-1(Cu/Pd) catalysts containing both micro- mesopores through the incorporation defect-generating linker 2,6-pyridyldicarboxylate (pydc). Pd NPs are formed by partial reduction Pd2+ sites pristine mixed-metal DE-HKUST-1(Cu/Pd) with methanol. size regime spatial distribution can be controlled amount framework-incorporated pydc. samples exhibit superior catalytic activity in aerobic oxidation cinnamyl alcohol as compared to parent HKUST-1.
