Noble metal nanoparticles or subnanometric particles confined in zeolites, i.e. Metal@zeolite, represent an important type of functional materials with typical core-shell structure. This type of materials have been known for decades and recently become a research hotspot due to their emerging applications in various fields. Remarkable achievements have been made dealing with the synthesis, characterization and applications of noble metal particles confined in zeolites. In this article, the most representative research progresses on Metal@zeolites are briefly reviewed, aiming to boost further researches on this topic. For the synthesis of Metal@zeolites, various strategies, such as direct synthesis from inorganic or ligand-assisted noble metal precursors, multi-step post-synthesis encapsulation and ion-exchange followed by reduction, are introduced and compared. For the characterization of Metal@zeolites, several most useful techniques, such as electron microscopy, X-ray based spectroscopy, infrared and fluorescence emission spectroscopy, have been recommended to check the successful confinement of noble metal particles in zeolite matrix and their unique physiochemical properties. For the applications of Metal@zeolites, catalysis and optics have been involved with emphasis on catalytic applications including the size-dependent catalytic properties, the sintering-resistance properties, the substrate shape-selective catalysis and catalysis modulation by zeolite microenvironment.
