A nanoreactor system comprising gold cores and silica hollow shells with empty inner space demonstrated. The Au@SiO2 yolk/shell nanoreactor is synthesized by selective etching of the gold cores in Au@SiO2 core/shell particles (see figure). This nanoreactor framework catalyzes the reduction of p-nitrophenol, exhibiting interesting size-dependent reaction property.
