Description
Smith, Luo, Millheim, and Millstone show how to control the structure of nanoparticles made of several metals at once. Controlling both the metal mix and the atom layout is hard when the metal sources reduce at very distinct natural rates. Standard methods then yield only phase separated particles instead of alloys or core shell forms.
The team varies how fast metal precursors are added, which changes their instant concentrations and thus their effective reduction rates. A quantitative model predicts how rates evolve with addition rate and points to the best settings. With the same precursors they make both core shell and alloy particles in two bimetal systems and in a five metal system, with control of the metal mix.
