Download or read book Thiolate capped Palladium Nanoparticles for Selective Catalytic Hydrogenation of Alkenes in the Presence of Another Reactive Functional Group written by Mohammed Mahdaly and published by . This book was released on 2019 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the preparation and catalysis of octanethiolate-capped palladium nanoparticles (C8 PdNP) and phenylethanethiolate-capped palladium nanoparticles (PhC2 PdNP) for chemoselective catalytic hydrogenation reactions of alkene groups in the presence of other reducible functionalities. Kinetic studies are performed and analyzed by 1H NMR spectroscopy to obtain clearer understandings of the catalytic activity. The noncovalent interactions between surface phenyl ligands and aromatic substrates are found to hinder the hydrogenation activity of PhC2 PdNP. In comparison, the C8 PdNP is discovered to be highly active and selective for hydrogenating alkene and alkyne groups without the reduction of other reactive functional groups such as nitro, halo, carbonyls, etc. under the mild reaction condition (room temperature and atmospheric pressure).

This book was released on 2019 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The reactions of palladium are invaluable to modern academic and industrial research, and nanotechnology is the foundation on which the next generation of materials is built upon. Unsupported thiolate-capped palladium nanoparticles were found to be highly substrate selective for alkene hydrogenation and isomerization. A modified Brust-Schiffrin reaction enabled the facile and convenient synthesis of a diverse set of ultra-small thiolate-capped nanoparticles. The physical properties of these nanoparticles were highly tunable due to the widespread availability of ligand precursors. Mechanistic evidence and insights reveal that steric and electronic effects from the ligand environment on the nanoparticle surface controlled reactivity by influencing alkene adsorption via [pi] bond coordination or di-[sigma] bond formation. Only alkenes close enough to the metal surface of the nanoparticles underwent reaction. Dienes with good overlapping p orbitals could overcome these steric effects on the deactivated palladium nanoparticle surfaces. A mechanistic model was built from these completed studies, and this model can be used to predict the selectivity of hydrogenation or isomerization in multiple classes of alkenes with varied substitution patterns. These palladium nanoparticles were also found to be capable of chemoselective alkene hydrogenation in the presence of functional groups that are known to be labile towards reduction by palladium.

Download or read book Catalytic Activity Versus Platinum palladium Nanoparticle Size in Low temperature Nitrogen Monoxide Reduction with Hydrogen written by Hui Li and published by . This book was released on 2010 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of experimental gamma-alumina (a-Al2O3) supported monometallic platinum (Pt), monometallic palladium (Pd), and bimetallic Pt-Pd catalysts were synthesized. The activities of these catalysts for nitrogen monoxide (NO) reduction by hydrogen (H2) were tested. The uncalcined catalysts were more active than their corresponding calcined catalysts. The uncalcined Pd-rich bimetallic catalysts were found to be synergistic and more active than pure Pt catalysts. The average particle sizes of all these catalysts were smaller than 3.5 nm, except that of the calcined Pd-rich catalyst. Nanoparticles observed in calcined catalysts were smaller than those in uncalcined catalysts. Sizes of nanoparticles in pure Pt and Pt-rich catalysts displayed normal distribution, while sizes of nanoparticles in pure Pd and Pd-rich catalysts displayed bimodal distribution. The various catalytic activities of these catalysts are explained by the differences in the sizes and surface compositions of nanoparticles formed in these catalysts.
