ABSTRACT Nanocatalysts behave homogeneously: The structural changes of two rationally designed heterogeneous Pd-based nanocatalysts were examined in a Suzuki reaction. By taking advantage of additional nanostructural characteristics, direct evidence of the leaching of soluble Pd was obtained; hence, the catalysis is promoted by oxidative addition of aryl halides to the nanoparticles.

    ABSTRACT: The separation and reuse of nanocatalysts remains a major challenge. Herein, we report a novel approach to prepare palladium nanowire array catalysts by reducting PdCl2 in the pores of anodic aluminum oxide (AAO) templates with backside Al sheets via a hydrothermal process. Suzuki coupling reactions and 4-nitrophenol (4-NP) reduction reactions were employed to study the catalytic activity of the nanocatalysts. The nanocatalysts demonstrated good activity, great thermal stability, easy separation and excellent reusability in both Suzuki reactions and 4-NP reductions.

    ABSTRACT: For improving stability and efficiency of noble metal nanomaterials, a straightforward one-step method was developed to synthesize Au–SiO2 composite nanospheres. Monodisperse hybrid silica nanospheres that had anilino-methyl on the surfaces were prepared first. The as-prepared hybrid silica nanospheres were then used to obtain Au nanocrystal through the redox reaction of HAuCl4 and anilino-methyl. This approach led to a better utilization of Au. By adjusting the surface morphologies and the particle sizes, the functional nanospheres displayed different surface-enhanced Raman scattering effects of Rhodamine 6G. The composite nanospheres showed high catalytic activity and good reusability in catalytic reduction of 4-nitrophenol because of their active gold surface.
