Dehydrogenation

A new catalyst from the U.S. Department of Energy’s Ames Laboratory and collaborators extracts hydrogen from hydrogen storage materials easily and efficiently. The process occurs at mild temperatures and under normal atmospheric conditions, without using metals or additives. The breakthrough offers more

Nanographene is a material that is anticipated to radically improve solar cells, fuel cells, LEDs and more. Typically the synthesis of this material has been imprecise and difficult to control. For the first time, researchers have discovered a simple way to gain precise control over the fabrication more

Researchers working within NCCR MARVEL have discovered a self-healing catalyst that can be used to release hydrogen through the hydrolytic dehydrogenation of ammonia borane. The catalyst, SION-X, is based on the abundant mineral Jacquesdietrichite, is sustainable, air stable and can be easily regene more

Pd/C, a widely accepted hydrogenation catalyst, is found to catalytically dehydrogenate 2-cinnamoylbenzoic acids to 3-benzylidene-3-H-isochroman-1,4-diones with H2 as the only byproduct. The synthetic reaction proceeds without oxidants and hydrogen acceptors, thereby representing an atom- and step-e more

Reaction of 8-amino-5,6,7,8-tetrahydroquinoline with RuCl2(PPh3)3 at room temperature affords the ruthenium(ii) chelate (8-NH2-C9H10N)RuCl2(PPh3)2 (E), in which the two triphenylphosphine ligands are disposed mutually cis. By contrast, when the reaction is performed at reflux ligand oxidation/dehydr more

Achieving rapid hydrogen desorption at low temperature is one of the main challenges in Mg-based alloys for hydrogen storage. Here, we report that the dehydrogenation process of Mg2NiH4 can be intrinsically improved using solid dissolution of titanium into its lattices. The hydrogen desorption is su more
