Cu2O Template Strategy for the Synthesis of Structure-Definable Noble Metal Alloy Mesocages

We have demonstrated a novel strategy of synthesizing noble metal alloy mesocages via a Cu2O template route. The efficiency of the current template route in producing alloy mesocages with various shapes (i.e., cube, octahedron, star) was evaluated in diverse systems of Pt, Pd, as well as Pt/Pd. The current approach offered a facile and effective protocol for the synthesis of hollow noble metal mesocages (even nanocages).
