摘要：

Right to the core: The design of nanocatalysts with maximized catalytic performance relies on control of the size, shape, and composition. The shell thickness of nanocrystals with core-shell structures can be controlled, thus enabling control over the nanocrystal electronic structure and catalytic properties. Monodisperse faceted icosahedral Au-Pd core-shell nanocrystals (see picture) were synthesized, and optimized for the oxidation of benzyl alcohol to benzaldehyde.
