or one catalyst with two or more active sites in one reaction system has recently attracted a widespread attention. [1][2][3][4][5][6] Of the many types of catalysis involving this strategy, synergistic catalysis has emerged as a powerful approach, in which the substrates concurrently activated by two or more distinct active sites. [1] This catalytic pathway simultaneously creates more than one reactive species, thereby the reaction energy barriers are distinctly lowered. [7] On the other hand, if selected judiciously, these active sites can collaborate with each other to enable many chemical reactions that are impossible or inefficient for traditional monoactive site catalysts. [4] Therefore, the development of highly efficiently synergetic catalysts with synergistic catalytic sites is of much interest as a way to improve the catalytic performance of heterogeneous catalyst.Loading of active metal species, such as isolated metal sites, metal nanoparticles (MNPs), or clusters, on solid carriers, is one of the most classical methodologies for synthesizing solid catalysts. The resulting materials, so-called supported catalysts, represent a simple and classical type of heterogeneous catalysts, which have been widely investigated and applied to many reactions in the past few decades. Undoubtedly, this type of catalyst is the first and one of most important candidates for designing and fabricating the synergetic catalysts. The problem, however, is that the active metal species dispersed on supports are easily leached and sintered at high temperatures, accompanied by the surface area loss and coke formation. [8][9][10][11][12] Regeneration of these deactivated supported catalysts is expensive and complex, particularly for the noble metal NPs catalysts. To deal with this issue, researchers have developed several strategies, such as strengthen metal-support interactions, coated the active NPs with thin shells of carbon or porous oxides, to stabilize catalytically active species on various supports. However, for the most of typical supports, such as carbon and oxides, the pore structures are poorly controlled, and considerable quantity of active metal sites are embedded in the bulk phase and unable to participate in reactions. In this context, crystalline porous materials (CPMs), mainly including metal-organic frameworks (MOFs) and zeolites, with high surface areas, tunable structures, uniform and well-defined pores/cavities, and feasible designability, have been proven to be a class of ideal supports to hinder sintering and provide access, through confining the active metal species in their nanopores. [8,[13][14][15][16][17][18][19][20][21][22][23][24] 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 metalorganic frameworks and zeolites with high scientific and industrial impact have recently been the subject of extensive research due to their essent...

“…For these reasons, the development of efficient catalysts for methanol synthesis by CO 2 hydrogenation has been extensively investigated, yet still remains a challenge as CO 2 is a stable gas molecule which requires a 6-electron reduction for conversion into methanol. So far, most research on CO 2 hydrogenation using MOF hybrid materials are related to CO (2-electron reduction) production,15,16 and there are few reports on CO 2 hydrogenation to methanol 7,13. Herein we describe highly active Cu nanoparticle composites for CO 2 hydrogenation to methanol, with activity controlled via charge transfer from Cu to UiO-66 by controlling the functional groups or metal species in the MOF for the first time.…”
