Palladium Supported on Bioinspired Materials as Catalysts for C–C Coupling Reactions

Polystyrene Supported [N-(Alanine) Sulfonamide]/Palladium Chloride: Synthesis, Characterization, for Heck Coupling Reactions

Abstract As a monomer, the [N-(alanine)] para-styrene sulfonamide (ASS) was prepared, from the reaction of para-styrene sulfonyl chloride and (S)-(+)-alanine in the presence of KOH 1M as a base, and CH3Cl was used as solvent. The monomer confirmed using FT-IR and 1H-NMR spectroscopy. Polystyrene [N-(alanine) sulfonamide] (PASS) was also prepared from the polymerization of [N-(alanine)] pa...

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 ...

Mild synthesis of Mesoporous silica supported ruthenium nanoparticles as heterogeneous catalysts in oxidative Wittig coupling reactions

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...

Study on spinel supported gold catalysts for alcohol oxidation reactions

Gold had been regarded as an inactive metal in catalysis due to its inert chemical nature. However, it was found that when gold is prepared as nanoparticles, it can exhibit surprisingly high activity for various reactions, especially for oxidation reactions [1]. In order to obtain gold nanoparticles (AuNPs), support is commonly used, which can not only help to avoid agglomeration of AuNPs, but ...
