New clues about a hydrogen fuel catalyst

07-Aug-2009

To use hydrogen as a clean energy source, some engineers want to pack hydrogen into a larger molecule, rather than compressing the gas into a tank. A gas flows easily out of a tank, but getting hydrogen out of a molecule requires a catalyst. Now, researchers reveal new details about one such ...

Transition to sustainable catalysis

Japanese scientists have discovered a cheap and enantioselective catalyst for asymmetric hydrogenation reactions

11-Nov-2008

Yasumasa Hamada and colleagues at Chiba University used a combination of nickel acetate and a commercially available phosphine ligand to catalyse the asymmetric hydrogenation of an alpha-amino-beta-keto ester hydrochloride. Although others have reported similar reactions, Hamada says this is the ...
