Dehydrogenation

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

Chemists spend a great deal of time and energy trying to get chemical reactions to begin or to speed up -- but sometimes it can be just as important to stop them before they go too far. In a recent study from the U.S. Department of Energy's (DOE) Argonne National Laboratory, chemists have identified more

For some crystalline catalysts, what you see on the surface is not always what you get in the bulk, according to two studies led by the Department of Energy's Oak Ridge National Laboratory. The investigators discovered that treating a complex oxide crystal with either heat or chemicals caused differ 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
