Catalysis Science & Technology at ISHHC XV

Carolin Ziebart, ISHHC XV poster prize winner

Catalysis Science & Technology was delighted to sponsor a poster prize at the International Symposium on Relations between Homogeneous and Heterogeneous Catalysis in Berlin in September.

The prize was awarded to Carolin Ziebart from the Leibniz-Institut für Katalysee.V., Rostock, Germany. The winning poster was entitled ‘Homogeneous catalyzed Hydrogenation of Bicarbonates and Carbon Dioxide to Formates, Alkyl Formates and Formamides with a well-defined Iron Catalyst’.

Congratulations to Carolin who works in Ralf Jackstell’s group, on homogenous catalysed carbon dioxide hydrogenation with non-noble metals.

A summary of the meeting can be found here: http://www.ishhc15.de/

Catalysis Science & Technology in C&EN

A Graham Hutchings paper in Catalysis Science & Technology has been highlighted by C&EN, in their Science & Technology Concentrates.

You can find their news story midway down the Science & Technology section, entitled ‘Gold catalyzes Esterifications’: http://pubs.acs.org/cen/currentissue.html

The article is about Professor Hutchings work on ‘Oxidative esterification of 1,2-propanediol using gold and gold-palladium supported nanoparticles‘. In the paper they use gold and gold palladium nanoparticles to make methyl lactate (used in cosmetics) and methyl pyruvate (used to treat diseases of the nervous system).

Hot Article: Stefan Kaskel investigates the partial oxidation of methane

Stefan Kaskel and team look at the partial oxidation and dry reformation of methane using a ceria/platinum catalyst on a silicon carbide support in this Catalysis Science & Technology Hot article.

This catalyst will be useful in the production of syngas, which is used in the Fischer-Tropsch process to make hydrocarbons and methanol (see our earlier post for other articles on this topic)

Stefan Kaskel is from Dresden University of Technology, Germany, visit his website to find out more about his research.

Catalysis Science & Technology Issue 7

The cover of Catalysis Science & Technology this month shows a small boy playing with various items such as spoons and forks with a mirror reflecting his play.

The image was made by Kazuaki Ishihara and colleagues from Nagoya University, the Sekisui Medical Co., and the Japan Science and Technology Agency. The cover image illustrates the research from their Catalysis Science & Technology paper in Issue 7 on ‘Catalytic enantioselective alkyl and aryl addition to aldehydes and ketones with organozinc reagents derived from alkyl Grignard reagents or arylboronic acids’ Catal. Sci. Technol., 2011, 1, 1149-1158

More about Professor Ishihara’s work can be found on his webpage.

The inside cover is by Liqiang Xu and co-workers from Shandong University, China and illustrates their work on ‘High yield synthesis of novel boron nitride submicro-boxes and their photocatalytic application under visible light irradiation’ Catal. Sci. Technol., 2011, 1, 1159-1165

See the full issue, which contains 2 perspectives, 7 communications and 16 full papers: Catalysis Science & Technology Issue 7

Hot Article: Accelerating the Baylis-Hillman

In this Catalysis Science & Technology Hot article Atul Chaskar and colleagues look at how the use of micelles can accelerate the rate of the Baylis-Hillman reaction.

The Baylis-Hillman reaction is used to form carbon-carbon bonds via the reaction of an aldehyde and an electron deficient olefin in the presence of DABCO.

Hot Article: Lignin-derived bio-oils

Bruce Gates and colleagues from the University of California look at the conversion of lignin-derived bio-oils by a platinum-aluminium oxide catalyst in this Catalysis Science & Technology Hot article.

This work focuses on the kinetics of the reaction, looking at what products are made and why, which will allow a better understanding of the bifunctional catalyst used. Lignocellulosic biomass is used to create biofuels, but the fundamental chemistry of bio-oil conversion like this is poorly understood, something which the team aim to correct.

Hot Article: Fine chemical catalysis in the liquid phase

This Catalysis Science & Technology Hot article showcases a collaboration between the University of Oxford and Johnson Matthey where they make a palladium catalyst with interstitial carbons for fine chemical catalysis in the liquid phase.

This paper will be included in the Heterogeneous Catalysis for Fine Chemicals theme issue, which focuses on  catalysis for fine chemicals synthesis, preparative chemistry and drug discovery, guest edited by Graham Hutchings and Mario Pagliaro.

Here they use a hydrothermal technique with glucose as the capping agent and supporting matrix, which when heated allows the carbon atoms to occupy the octahedral holes in the palladium framework.

Shik Chi Tsang from the University of Oxford comments, that in this research the catalyst they create will ‘prove highly beneficial for liquid phase hydrogenations of alkyne to alkene, one of the key steps in the pharmaceuticals, fragrances and fine chemical catalysis’.

Hot Article: Nanocrystalline mixed oxide catalysts

In this Catalysis Science & Technology Hot article Houshang Alamdari and colleagues from the University of Laval, Canada, use a mechanosynthesis technique to make nanocrystalline hexaaluminate-type mixed oxides for use as heterogeneous catalysts.

The team make a material with high surface area and catalytic activity, with crystals of about 20nm. The technique is great because it is easy to scale-up and does not require waste treatment or complicated process control.

Similar materials have been used as catalysts in the high temperature catalytic combustion of methane, so perhaps this technique will find a future there!

Hot Article: Colloidal platinum nanoparticle catalysts

In this Catalysis Science & Technology Hot article Amanda Barnard and colleagues present the first nanoscale phase diagram of colloidal nanoparticle catalysts made of platinum.

They are investigating how to optimise platinum catalysts by modifying their shape, and so use a theoretical nanomorphology model previously used on nanogold to understand platinum nanocatalysts.

Nanocatalysts like this are desirable because they allow a smaller amount of a valuable metal to be used, making them cheaper and more sustainable.
