Monodisperse Yolk-Shell Nanoparticles with a Hierarchical Porous Structure for Delivery Vehicles and Nanoreactors

摘要

Core-shell and hollow structures are powerful platforms for controlled release, confined nanocatalysis, and optical and electronic applications.A hybrid of core-shell and hollow structures, a special class of core-shell structure with a distinctive core@void@shell configuration, which are called yolk-shell or rattle-type structures, have attracted tremendous interest in recent years. With the unique properties of movable cores, interstitial hollow spaces, and the functionality of shells, yolk-shell structures have great potential for application in various fields, such as nanoreactors,bio-medicine, lithium-ion batteries,and photocatalysis.
