Abstract:
In recent years, the development of efficient catalysts for photo-/electro-catalytic CO2 reduction reaction (CO2RR) has become a major research focus due to growing environmental concerns and energy demands. Dual-atom catalysts (DACs), composed of two metal atoms with suitable metal-metal distance integrated into the supports, have shown great promise in enhancing catalytic performance via the dual-metal synergistic catalysis (DMSC) effect. This review highlights the advancements in Metal-organic framework (MOF)-based DACs, which combine the high atomic efficiency of DACs with tunable and defined structures and high metal loadings. In this review, we summarized the recent developments on the synthesis strategies of MOF-based DACs and their applications in CO2RR, focusing on the role of DMSC effect in improving catalytic activity, stability, and selectivity. Additionally, we also discuss the influence of the local electronic structure, coordination environment, and metal atom interactions on catalytic performance. This review aims to provide a comprehensive understanding of MOF-based DACs and offers insights into their future potential in sustainable energy conversion.

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
