Abstract:

Branched palladium nanostructures were synthesized under microwave irradiation using polyvinylpyrrolidone (PVP) as stabilizer and benzyl glycol as the reducing agent of H2PdCl4. Morphology and structure were characterized by transmission electron microscopy (TEM), X-ray powder diffraction (XRD), and X-ray photoelectron spectroscopy (XPS), and showed that the branched Pd nanostructures were self-assemblies of hundreds of small spherical nanoparticles. Furthermore, catalytic properties of the branched Pd nanostructures were investigated for the hydrogenation of nitrobenzene, which indicated that the catalytic activity of the branched Pd nanostructures for this reaction is higher than that of a conventional Pd/C catalyst.
