Abstract: Au Pd alloy catalysts were successfully loaded into amine-functionalized metal-organic framework (MOF, UiO-66-NH2) via direct absorption/reduction method. The existence of Pd in the alloy was revealed by using in situ fourier transform infrared spectroscopy (FTIR) with CO as probe molecules. The X-ray diffraction (XRD) and transmission electron microscopy (TEM) results demonstrated the Au Pd alloys were well dispersed within the robust UiO-66-NH2. Au Pd alloy nanoparticles with low Pd content were well dispersed within UiO-66-NH2 and exhibited high stability and selectivity for N-benzylaniline (98%) in the direct reductive amination with benzaldehyde and nitrobenzene.
