All that glitters – gold and palladium serve catalysis needs

Sara Coles is a guest web-writer for Catalysis Science & Technology. She currently works for Johnson Matthey in Royston, UK.


Gold-palladium nanoparticles are hot stuff when it comes to catalysis. Catalysis Science and Technology’s themed issue, entitled ‘Gold Catalysis’, highlights just three examples of the many studies that regularly appear in the literature.

A minireview from Pasi Paalanen et al., Utrecht University, gives an overview of recent developments in the synthesis of supported gold-based bimetallic nanoparticles for catalytic applications. They focus on three major structural features to be characterised and, where possible, controlled: size, composition and nanostructure. They highlight selected literature examples in which gold-palladium nanoparticles were found to be active for reactions such as CO oxidation, vinyl acetate synthesis, cyclotrimerization of acetylene to benzene, selective oxidation of alcohols to aldehydes or ketones, direct synthesis of hydrogen peroxide, hydrocarbon hydrogenation, oxidation of primary C–H bonds, hydrodechlorination and hydrodesulfurization.

chloronitrobenzene hydrogenation and hydrogen peroxide synthesis over gold palladium nanoparticlesMeanwhile Elena Corbos and her colleagues at Johnson Matthey Technology Centre, in collaboration with Synchrotron Soleil, France, and University College London, present some original research on the preparation of bimetallic PdAu nanocatalysts. They tested the catalysts for the selective hydrogenation of 2-chloronitrobenzene to 2-chloroaniline and the direct formation of hydrogen peroxide. They found that a Pd-rich surface offered superior selectivity and reaction rates for 2-chloronitrobenzene hydrogenation, while for hydrogen peroxide synthesis, an optimal quantity of gold was required to ensure high productivity.

Tatsumi Ishihara et al., Kyushu University, Japan, carried out synthesis of hydrogen peroxide by direct oxidation of hydrogen in air on gold-palladium/titania. They report that the H2 conversion and H2O2 selectivity were strongly affected by the crystal phase of the titania. With increasing H2 pressure, H2O2 selectivity increased on AuPd/rutile TiO2 and the yield of became higher than on brookite or anatase TiO2 at 1.0 MPa. The effects of fluorinated hydrocarbon addition to reaction media were also studied.

Oxidoreductases reduce bulk-bulky hydroxy-ketones to give optically active 1,2-diols

Challenging enzymatic stereoselective reduction of sterically demanding substrates.

Challenging enzymatic stereoselective reduction of sterically demanding substrates.

Dörte Rother and colleagues have identified alcohol dehydrogenases that can be used for the stereoselective reduction of some sterically demanding ketones, under mild conditions.  The team initially screened eight enzymes, with alcohol dehydrogenase from Ralstonia sp. giving the best results.  Compounds with two chiral centres have important ‘building block’ applications as synthons for catalysts, pharmaceuticals and agrochemicals and this study demonstrates the high potential of biocatalysts in this area.

Biodegradation pathway for α,β-unsaturated haloesters

Kurt Faber and colleagues from the Unviersity of Graz report the reductive dehalogenation of  β-haloacrylic ester derivatives using members of the ‘Old Yellow Enzyme’ family of flavoproteins in this HOT Catalysis Science & Technology communication.  They have combined the ‘reductive activity of ene-reductases with the spontaneous β-elimination of hydohalous acid from the unstable (saturated) intermediates’ in this biodegradation pathway.  Such work is important for its application to the disposal of organic halogenated materials that have negative effects on the environment.

This is another fantastic article that is due to be included in our upcoming Biocatalysis themed issue.  Download the communication today – it’s free

PERSPECTIVE: Imidazolium-derived organosilicas for catalysis

This perspective focuses on the catalytic uses of imidazolium derivatives grafted on to silicas, including metal catalysts (complexes and nanoparticles) and metal-free ones.  It is intended to help in inspiring future developments and interest in the growing field of catalysis by supported imidazolium salts and NHC (N-heterocyclic carbenes) complexes based on organosilicas.
