▎ 摘　　要

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.
