Nanoalloys

Shaping multimetallic nanoparticles

Nature Synthesis (2023)Cite this article

Subjects

A kinetically controlled solution-phase synthesis produces nanoparticles of defined shape and multimetallic surface composition for catalytic applications.

In heterogeneous catalysis, activity and selectivity depend on the binding energies of surface adsorbates and on the kinetic barriers between the elementary steps in the reaction. If focusing on metal nanoparticles, which are frequently used as catalysts, intuitively, one would expect that the precise combination of metals on their surfaces could lead to desired catalytic outcomes. Indeed, advances in high-throughput first-principles theory calculations have led to predictions of improved performance if certain combinations of different metals, or specific strain states, can be produced on specific surface orientations1.
