Surface Diffusion of Palladium and Its Prevention over Supported Palladium Catalyst

Synthesis of nanostructured palladium, palladium oxide and palladium-palladium oxide nanocomposite by the gel combustion method and application as catalyst of hydrogen release

This paper presents a new gel combustion method to synthesize palladium nanoparticles, palladium oxide (PdO) nanoparticles and palladium-palladium oxide nanocomposites. In the proposed method, there are some effective parameters including palladium chloride concentration, polyvinyl alcohol (PVA) concentration, acid concentration, solvent composition and combustion temperature that their values ...

Recovery of Palladium from Spent Activated Carbon-Supported Palladium Catalysts

TÜBİTAK Marmara Research Center, Chemistry Institute, 41470 Gebze, Kocaeli, Turkey Email: [email protected] Activated carbon-supported palladium catalysts are liable to progressive deactivation even in the absence of any gaseous contaminants during the oxidation of hydrogen under ambient conditions. The high value of palladium coupled with environmental considerations means that n...

Synthesis of Supported Palladium Catalysts

The synthesis of supported palladium (Pd) catalysts is reviewed with emphasis on the chemistry of catalyst synthesis, oxidic and carbon support properties and case studies in the period 1990-2000. For the application of Pd onto oxidic supports aqueous precursor solutions are frequently used. The charge of the Pd precursor and the iso-electric point of the support are important properties since ...

Supported palladium nanoparticles: an efficient catalyst for the direct formation of H2O2 from H2 and O2.

Melting and Structural Evolution of Palladium and Graphite-supported Palladium Nanoclusters: A Molecular Dynamics Simulation Study

The thermal behavior of palladium nanoclusters of different sizes, in free space and on a graphite surface, was studied using molecular dynamics simulations. The Sutton-Chen many-body potential function was utilized for the metal, and the structured graphite surface was represented by a simple Lennard-Jones model. Changes in thermodynamic and structural properties upon heating and cooling in th...
