Аннотация: The review is devoted to the analysis of the strategies used for the design and preparation of zeoliteencapsulated subnanometric metal clusters. Nowadays this topic is often considered as one of the mostrapidly developing in heterogeneous catalysis. On the one hand, it is due to the great fundamental interestto the structure and properties of such materials and, on the other hand, it is related to their unique catalytic properties and great perspectives for their application in a number of important heterogeneous catalytic reactions aimed at the conversion of non-conventional feedstocks and building a low-carbon (decarbonized) economy. The application of metal-containing zeolites allows the challenges related to thedevelopment of novel tandem processes, which require simultaneous proceeding of several catalyticreactions over one catalyst, to be addressed. The coupling of zeolites and metals in a single catalystallows for fine-tuning the properties of tandem catalysts both by engineering the nature, state and localization of the metal active sites, and by mastering the unique porous structure of the zeolites with activesites of different nature. The contribution presents the methodological aspects of the synthesis of thedescribed systems, highlighting their advantages, limitations and problems related to their applications. Inparticular, both novel methods of metal encapsulation and conventional ones known for decades areanalyzed and systematized. Special attention is paid to the conditions under which simple conventionalmethods allow the encapsulation of nanoclusters in zeolite. As a result, the recommendations on themost preferable approaches for obtaining specific zeolite–metal combinations are given and promisingdirections for the development of synthesis methods are highlighted.
