Selective growth of metal particles on ZnO nanopyramids via a one-pot synthesis

Hybrid nanostructures of metal (Cu, Au, Ag)–ZnO nanopyramids were synthesized. These hybrid nanostructures possess two distinct morphologies where the metal can be selectively attached to either the base or the tip of the ZnO pyramids. This is the first time that such morphologies are reported for Cu–ZnO and Ag–ZnO hybrid nanostructures.
