摘要：

Raney copper catalysts were modified by addition of ruthenium by means of an oxido-reduction reaction between copper surface and ruthenium chloride in aqueous solution. Energy dispersive spectroscopy fitted to a STEM unit allowed to conclude that the active sites for the selective conversion of glucitol into 1,4-3,6-dianhydroglucitol are composed of ruthenium and chlorine located on low coordinated copper atoms.
