Au−Pd alloy catalysts were successfully loaded into amine‐functionalized metal‐organic framework (MOF, UiO‐66‐NH 2 ) 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‐NH 2 . Au−Pd alloy nanoparticles with low Pd content were well dispersed within UiO‐66‐NH 2 and exhibited high stability and selectivity for N‐benzylaniline (98%) in the direct reductive amination with benzaldehyde and nitrobenzene.
