Core-shell metal nanoparticles successful in solvent-free aerobic oxidation

Graham Hutchings, Christopher Kiely et al. have found that trimetallic Au-Pd-Pt nanoparticles supported on activated carbon are highly active and selective catalysts for the solvent-free aerobic oxidation of benzyl alcohol.

In their recently published paper, they demonstrate that when a small amount of Pt metal is alloyed into Au-Pd sols, a high selectivity toward benzaldehyde can be achieved while still preserving high conversion levels. Their work is an exciting step towards making the industrially very important process of oxidation of primary alcohols to aldehydes cheap and environmentally friendly.

Switching-off toluene formation in the solvent-free oxidation of benzyl alcohol using supported trimetallic Au–Pd–Pt nanoparticles
Qian He, Peter J. Miedziak, Lokesh Kesavan, Nikolaos Dimitratos, Meenakshisundaram Sankar, Jose Antonio Lopez-Sanchez, Michael M. Forde, Jennifer K. Edwards, David W. Knight, Stuart H. Taylor, Christopher J. Kiely and Graham J. Hutchings
DOI: 10.1039/C2FD20153D

They recently presented and discussed their paper at the Faraday 162 meeting in Berlin.

Gold intermediate found in green synthesis

A gold ketenylidene species (Au2=C=C=O) has been identified as a key intermediate in the partial oxidation of acetic acid over a gold/TiO2 catalyst – a reaction that could have important consequences for environmentally friendly organic synthesis. Gold and TiO2 both play a part in the catalysis, with C–H bond scission occurring at the former and C–O scission at the latter.

Such reactions could represent important routes to the de-oxygenation of acids and esters derived from bio-renewable intermediates, and hence the green manufacture of important bulk chemicals.

Mechanistic insights into the partial oxidation of acetic acid by O2 at the dual perimeter sites of a Au/TiO2 catalyst
Matthew Neurock, Isabel Xiaoye Green, Wenjie Tang and John Yates
DOI: 10.1039/C3FD00002H

This exciting work will be discussed FD162: Fabrication, Structure and Reactivity of Anchored Nanoparticles.

Filming the motions of individual lipids

Image of observation area, lipid bilayer and cover glassSuper resolution microscopy breaks the diffraction limit. Professor Dr Stefan Hell is credited for the development of STED or stimulated emission depletion microscopy. In this paper arising from the Faraday Discussion on Lipids & Membrane Biophysics STED is used in combination with FCS or fluorescence correlation spectroscopy to follow the diffusion of dye labeled lipids in membrane model systems on glass and mica.

Super resolution microscopy is used to study the diffusion of labelled lipids, two labels are employed, one that localises in the liquid ordered and one that localises in the liquid disordered phase of the lipid membrane model. Through STED, and with the two new probes introduced, the rate of 2D diffusion in the membrane can be measured. As the localisation of the two probes is different, a map of the disordered and ordered domains can be generated.

Ion Specific Hofmeister Effects: FD160

Figure reproduced from the Introductory Lecture of FD160 (DOI: 10.1039/C2FD20128C)

Figure reproduced from the Introductory Lecture of FD160 (DOI: 10.1039/C2FD20128C)

If you take two glasses of water and dissolve sodium chloride in the one and sodium iodide in the other, I can tell you that in the first glass you have a deficiency of anions in the water-air interface and an accumulation of negative ions in the same interface in the latter glass. I can also tell you that if you dip a glass stirrer into one glass it will become negatively charged, where it in the other will get a positively charged. The last piece of wonder I can share is that if you use a plastic spoon instead the effects are reversed.

The examples I gave above are all examples of Hofmeister effects, where the nature of a small ion dictates specific events to occur in larger systems. The example with iodide and chloride are not the most extreme and the effects described above are small. The extreme cases include sulphate, perchlorate and hexafluorophosphate, the former is extremely hydrophilic and the two other are very lipophilic. Cations are an altogether different story all-together.

The importance of the Hofmeister effects are not to be underestimated as all biological processes and structures have to exist in ion-rich environments. Strip away the ions or introduce large quantities of an alien small ion and the processes and structures are disrupted. Killing an organism by introducing potassium is an easy experiment. Understanding the effects of chloride, bromide and sodium on every single piece of the biological machinery is much more challenging. The challenge is being met by the group of researchers who attended the 160th Faraday Discussion on Ion Specific Hofmeister Effects. Their latest findings and a thorough introduction to the subject is published in the recent issue of Faraday Discussions.

Much, much more information and many insights can be gleaned in the themes issue of Faraday Discussion on Ion Specific Hofmeister Effects.

HOT article on surface interactions of gold to be discussed at FD162 – Register to join us

Japanese scientists have reported their work on the interactions of gold species on titania in a Faraday Discussions Accepted Manuscript. They found that the Au-anion interaction is mainly responsible for stabilising Au atoms on a thiol modified titania surface, while only Au55 clusters were found on a bare titania surface.

This is important in developing an understanding of how such systems behave during catalytic reactions, and suggests that surface modification may be a useful method for controlling the Au species on titania.

This paper will be among those discussed at the upcoming Faraday Discussion 162: Fabrication, Structure and Reactivity of Anchored Nanoparticles in Berlin.

Registration for this exciting is event is now open.

All delegates will have the opportunity to present their views on the Discussion papers and their own new research. All the presented papers and the discussion will be published together in the Faraday Discussion volume. The latest Impact Factor is 5.0.

Register today to attend Faraday Discussion 162: Fabrication, Structure and Reactivity of Anchored Nanoparticles.
