Synthetic control over lattice strain in trimetallic AuCu-core Pt-shell nanoparticles.

ABSTRACT: Core-shell nanoparticles can exhibit strongly enhanced performances in electro-, photo- and thermal catalysis. Lattice strain plays a key role in this and is induced by the mismatch between the crystal structure of the core and the shell metal. However, investigating the impact of lattice strain has been challenging due to the lack of a material system in which lattice strain can be controlled systematically, hampering further progress in the field of core-shell catalysis. In this work, we achieve such a core-shell nanoparticle system through the colloidal synthesis of trimetallic Pt-shell Au_1-xCu_x-core nanoparticles. Our seed-mediated growth methodology yields well-defined Au_1-xCu_x-cores, tunable in composition from 0
