Bimetallic nanoalloys have attracted great research interest in the past decades by virtue of their tunable metal-metal synergies. The preparation of well-defined bimetallic nanoalloys largely relies on the use of capping ligands, which brings a great challenge to utilize the surface-accessible active sites and/or tailor bimetallic-support interactions. In the current paper, surface-clean, thermally stable and monodisperse PdAu nanoalloys confined in mesoporous TiO2 (PdAu@mTiO(2)) were prepared using evaporation-induced self-assembly with two colloidal templates. The hydrogenation activity of PdAu@mTiO(2) was demonstrated to be approximately 6 times higher than that of PdAu nanoalloys supported on mesoporous silica due to the bimetallic-support interactions. Our method is expected to open up new opportunities to synthesize ligand-free and stable bimetallic nanoalloys with tailored bimetallic-support interactions for highly efficient catalysis.
