Issue 1 2012 of Green Chemistry is now online!

The front cover of the issue highlights work by Graham Hutchings and colleagues from Cardiff University, UK, who prepared several Au-Pd exchanged supported Cs-heteropolyacid catalysts and applied them to the direct synthesis of hydrogen peroxide from H2 and O2 in water under ambient conditions. 

The inside front cover features work by George Huber and co-workers from the University of Massachusetts-Amherst, USA and Southeast University, China, who report the catalytic fast pyrolysis of wood and alcohol mistures in a fluidized bed reactor.  By looking at the various reaction parameters, the authors demonstrate that catalytic fast pyrolysis can selectively produce a mixture of compounds and that the overall yield is a function of the hydrigen to carbon effective ratio.

Green Chemistry issue 12 is now online! 

The front cover of this issue features work by Sibudjing Kawi and W. Thitsartarn from the National University of Singapore.  They report a stable and active CaO-CeO₂ catalyst, prepared by simple gel formation viaa co-precipitation method, which was applied to the transesterification of oil to biodiesel.  The catalyst could be reused up to 18 times without significant loss of activity and showed only low amounts of leaching.  Find out more by reading the full article ‘An active and stable CaO–CeO₂catalyst for transesterification of oil to biodiesel.’

The inside front cover highlights work from Jérôme Husson and co-workers from the Université de Franche-Comté.  They report a new synthesis route to 4,4′,4′′-tricarboxy-2,2′:6′,2′′-terpyridine, a ligand that is a component of the “Black-dye” sensitizer for dye-sensitized solar cells.  The route developed by Husson has a lower ecological impact with respect to atom economy, yield, solvent and chemicals used and wastes generated, compared to the previously reported method.  Find out more by reading the full article ‘A more efficient synthesis of 4,4′,4′′-tricarboxy-2,2′:6′,2′′-terpyridine.’
