Abstract: 

The design and development of efficient catalytic materials with  synergistic catalytic sites always has long been known to be a thrilling  and very dynamic research field. Crystalline porous materials (CPMs)  mainly including metal-organic frameworks and zeolites with high  scientific and industrial impact have recently been the subject of  extensive research due to their essential role in modern chemical  industrial processes. The rational incorporation of guest species in  CPMs can synergize the respective strengths of these components and  allow them to collaborate with each other for synergistic catalysis,  leading to enhanced catalytic activity, selectivity, and stability in a  broad range of catalytic processes. In this review, the recent advances  in the development of CPMs-confined active metal species, including  metal nanoparticles, metal/metal oxides heteroparticles, metal oxide,  subnanometric metal clusters, and polyoxometalates, for heterogeneous  catalysis, with a particular focus on synergistic effects between active  components that result in an enhanced performance are highlighted.  Insights into catalysts design strategies, host-guest interactions, and  structure-property relationships have been illustrated in detail.  Finally, the existing challenges and possible development directions in  CPMs-based encapsulation-structured synergistic catalysts are discussed.
