A simple one-step approach for the preparation of highly monodispersed nano copper(0) stabilized on alumina [Cu(0)/Al2O3] by thermal reduction of copper-aluminium hydrotalcite (Cu-Al HT) under a hydrogen atmosphere is described. The transformation of Cu-Al HT to Cu(0)/Al 2O3 occurrs via dehydroxylation of divalent and trivalent metal hydroxides and decarboxylation of carbonate anions present in the interlayers of hydrotalcite, as confirmed by XPS, XANES, XRD and TEM analysis. Cu(0)/Al2O3 nano composites were used as an efficient catalyst in the C-C coupling of deactivated aryl chlorides. The high efficiency and reusability exhibited by Cu(0)/Al2O3 outline its potential as an alternative over traditional noble metal-based catalysts in C-C coupling reactions. Copyright
