Congratulations, a new paper from Dr. Yuchao Chai, titled "Nobel metal particles confined in zeolites: Synthesis, characterization and applications" was accepted by Advanced Science.

Noblemetal 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 researchhotspot due to their emerging applications in various fields. Remarkable achievementshave been made dealing with the synthesis, characterization and applications ofnoble metal particles confined in zeolites. In this article, the most representativeresearch progresses on Metal@zeolites are briefly reviewed, aiming to boost furtherresearches 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, severalmost useful techniques, such as electron microscopy, X-ray based spectroscopy,infrared and fluorescence emission spectroscopy, have been recommended to checkthe successful confinement of noble metal particles in zeolite matrix and theirunique physiochemical properties. For the applications of Metal@zeolites,catalysis and optics have been involved with emphasis on catalytic applicationsincluding the size-dependent catalytic properties, the sintering-resistance properties,the substrate shape-selective catalysis and catalysis modulation by zeolite microenvironment.
