Compared withthe core−shell nanostructure, in which the shell is directly onthe metal surface, the cavity between the core and the shell inthe yolk−shell structure not only reserves a larger exposedmetal surface for the reactants but also makes the reactantsinteract with the surface more homogeneously.
