Palladium-gold catalysts for H2O2 direct synthesis at room temperature and atmospheric pressure
Introduction Hydrogen peroxide has always been considered a very interesting and environmentally friendly oxidant with applications confined mainly in unselective sectors such as the paper and textile industry and the treatment of waste waters. More recent applications, related to the discovery of TS-1 molecular sieve, are in the large scale selective oxidation processes for the chemical indust...
متن کاملSilver-palladium catalysts for the direct synthesis of hydrogen peroxide.
A series of bimetallic silver-palladium catalysts supported on titania were prepared by wet impregnation and assessed for the direct synthesis of hydrogen peroxide, and its subsequent side reactions. The addition of silver to a palladium catalyst was found to significantly decrease hydrogen peroxide productivity and hydrogenation, but crucially increase the rate of decomposition. The decomposit...

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 ...
متن کاملPalladium Catalysts in Organic Synthesis
The main catalysts which are traditionally used for the hydrogenation of organic compounds are supported platinum group metals, and while these heterogeneous catalysts are generally not effective in carbon-carbon bond forming reactions, there has been a growing interest in recent years in soluble complexes of the platinum group metals for use as catalysts in organic synthesis. Rhodium catalysed...
