Effect of the Size of Polyacrylamide-Stabilized Palladium Nanoparticles Supported on γ-Fe2O3 on Their Catalytic Properties in the Hydrogenation of Phenylacetylene

Hydrogenation catalysts derived from palladium nanoparticles varying in size supported on maghemite (γ-Fe 2 O 3 ) were obtained by varying the concentration of K 2 PdCl 4 and polyacrylamide as well as the solution pH during catalyst preparation. These catalysts were characterized by electron microsc...

More Information
Summary:Hydrogenation catalysts derived from palladium nanoparticles varying in size supported on maghemite (γ-Fe 2 O 3 ) were obtained by varying the concentration of K 2 PdCl 4 and polyacrylamide as well as the solution pH during catalyst preparation. These catalysts were characterized by electron microscopy, dynamic light scattering, energy dispersive analysis, and IR spectroscopy. Decreasing the size of the palladium nanoparticles leads to enhanced activity of the catalyst in the hydrogenation of phenylacetylene by molecular hydrogen
