A novel route with a Cu(II)-MOF-derived structure to synthesize Cu/Cu2O NPs@graphene: the electron transfer leads to the synergistic effect of the Cu(0)-Cu(I) phase for an effective catalysis of the Sonogashira cross-coupling reactions

A uniformly dispersed two-phase Cu/Cu2O NPs@graphene was obtained via an innovative take and off synthesis strategy with a Cu-MOF-derived jacket structure. The electron transfer between the Cu phase and Cu2O phase leads to the synergistic effect of the Cu(0)-Cu(I) phase for an efficient catalysis of the Sonogashira cross-coupling reactions.
