title: Pd-Cu(2)O and Ag-Cu(2)O hybrid concave nanomaterials for an effective synergistic catalyst.
abstract: Palladium and silver salts were combined with Cu2 O octadecahedra in concave heterostructures. The formation of concave faces involved selective oxidative etching of Cu2 O on the {100} faces and in situ growth of Pd/Ag on different sites. The structures showed superior catalytic activities to both single domains and their mixtures in a model Sonogashira-type organic reaction.
