Semihydrogenation of Phenylacetylene Catalyzed by Palladium Nanoparticles Supported on Organic Group Modified Silica

Abstract:

Article Preview

Different Pd precursors were used to prepare Pd catalysts supported by using organic group modified silica. The catalysts were characterized by TEM and FTIR analysis. The results indicated that the small Pd nanoparticles (1-2nm) were achieved using Pd precursors with negative charge, while the size of Pd particle increased to 2-4 nm using Pd precursors with positive charge. For semihydrogenation of phenylacetylene, large-sized Pd partcles (2-4nm) exhibited high styrene selectivity compared with small-sized ones (1-2nm).
