A metal-organic framework (MOF), MIL-101, whose high chemical resistance structure, high surface area and large porous channels allowing nanoparticles encapsulation for catalysis application, was synthesized by using the hydrothermal technique. The noble metal nanoparticles of gold (Au), palladium (Pd) and platinum (Pt) were synthesized by using poly(N-vinyl-2-pyrrolidone) (PVP) as a stabilizing agent. Afterward, the resulted Au:PVP, Pd:PVP, Pt:PVP metal nanoparticles were then supported onto the structure of MIL-101 by using a simple colloidal deposition method. After calcination, the obtained Au/MIL-101, Pd/MIL-101, Pt/MIL-101 samples were then characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and N2 adsorption/desorption characterization methods. It is found that the metal nanoparticles are well supported both in the porous channels and onto the external surface of MIL-101. The catalytic activity and selectivity of the obtained metal/MIL-101 hybrid materials in the aerobic oxidation of alcohols will be discussed.
