Book excerpt: The high price of platinum currently employed as catalyst for the oxygen reduction reaction in fuel cells represents an obstacle for a widespread usage of these cells. The development of bimetallic particles, reducing the quantity of platinum is a promising solution to increase the viability of the cells and to reduce their price. In this doctoral thesis, palladium was used as a second metal to synthesize bimetallic particles with easy methods. The role of bromide on the properties and performances of the palladium-platinum clusters with a nanoflowers structure was investigated (Chapter 2) and the effect of the time of synthesis on particles prepared by galvanic replacement was analyzed (Chapters 3 and 4). In the end, the formation/dissolution of oxide at the surface of core-shell palladium-platinum nanoparticles was examined (Chapter 4). ...

Download or read book Superlattices of Platinum and Palladium Nanoparticles written by and published by . This book was released on 2000 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors have used a nonionic inverse micelle synthesis technique to form nanoclusters of platinum and palladium. These nanoclusters can be rendered hydrophobic or hydrophilic by the appropriate choice of capping ligand. Unlike Au nanoclusters, Pt nanoclusters show great stability with thiol ligands in aqueous media. Alkane thiols, with alkane chains ranging from C6 to C1 were used as hydrophobic ligands, and with some of these they were able to form 2-D and/or 3-D superlattices of Pt nanoclusters as small as 2.7 nm in diameter. Image processing techniques were developed to reliably extract from transmission electron micrographs (TEMs) the particle size distribution, and information about the superlattice domains and their boundaries. The latter permits one to compute the intradomain vector pair correlation function of the particle centers, from which they can accurately determine the lattice spacing and the coherent domain size. From these data the gap between the particles in the coherent domains can be determined as a function of the thiol chain length. It is found that as the thiol chain length increases, the gaps between particles within superlattice domains increases, but more slowly than one might expect, possibly indicating thiol chain interdigitation.

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.

Download or read book Gold Nanoparticles in Biomedical Applications written by Lev Dykman and published by CRC Press. This book was released on 2017-12-12 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses fabrication of functionalized gold nanoparticles (GNPs) and multifunctional nanocomposites, their optical properties, and applications in biological studies. This is the very first book of its kind to comprehensively discuss published data on in vitro and in vivo biodistribution, toxicity, and uptake of GNP by mammalian cells providing a systematization of data over the GNP types and parameters, their surface functionalization, animal and cell models. As distinct from other related books, Gold Nanoparticles in Biomedical Applications discusses the immunological properties of GNPs and summarizes their applications as an antigen carrier and adjuvant in immunization for the preparation of antibodies in vivo. Although the potential of GNPs in nanobiotechnology has been recognized for the past decade, new insights into the unique properties of multifunctional nanostructures have recently emerged. With these developments in mind, this book unites ground breaking experimental data with a discussion of hybrid nanoparticle systems that combine different nanomaterials to create multifunctional structures. These novel hybrids constitute the material basis of theranostics, bringing together the advanced properties of functionalized GNPs and composites into a single multifunctional nanostructure with simultaneous diagnostic and therapeutic functions. Such nanohybrids can be physically and chemically tailored for a particular organ, disease, and patient thus making personalized medicine available.

Download or read book Evidence for the Formation of Nitrogen Rich Platinum and Palladium Nitride Nanoparticles written by and published by . This book was released on 2013 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here, we report evidence for the formation of nitrogen-rich precious metal nanoparticles (Pt, Pd) prepared by reactive sputtering of the pure metal in a N2 plasma. The composition of the nanoparticles varies as a function of particle size and growth conditions. For the smallest particles the nitrogen content appears to be as high as 6.7 N atoms for each Pd atom or 5.9 N atoms for each Pt atom whereas bulk films have nominal compositions of Pt7.3N and Pd2.5N. The nanoparticles are metastable in air and moisture, slowly decomposing over several years. This paper describes the synthesis of these materials along with experimental evidence of the composition, oxidation state, and growth modes. Moreover, the catalytic properties of these N-rich nanoparticles were accessed by rotating disk electrode electrochemical studies, the liquid phase oxidation of benzyl alcohol and gas phase CO oxidation and support the experimental evidence for the materials composition.

Download or read book Palladium platinum Core shell Electrocatalysts for Oxygen Reduction Reaction Prepared with the Assistance of Citric Acid written by and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Core-shell structure is a promising alternative to solid platinum (Pt) nanoparticles as electrocatalyst for oxygen reduction reaction (ORR) in proton exchange membrane fuel cells (PEMFCs). A simple method of preparing palladium (Pd)-platinum (Pt) core-shell catalysts (Pd@Pt/C) in a gram-batch was developed with the assistance of citric acid. The Pt shell deposition involves three different pathways: galvanic displacement reaction between Pd atoms and Pt cations, chemical reduction by citric acid, and reduction by negative charges on Pd surfaces. The uniform ultrathin (~0.4 nm) Pt shell was characterized by in situ X-ray diffraction (XRD) and high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) images combined with electron energy loss spectroscopy (EELS). Compared with state-of-the-art Pt/C, the Pd@Pt/C core-shell catalyst showed 4 times higher Pt mass activity and much better durability upon potential cycling. As a result, both the mass activity and durability were comparable to that of Pd@Pt/C synthesized by a Cu-mediated-Pt-displacement method, which is more complicated and difficult for mass production.
