Abstract:
Electronic metal-support interaction (EMSI) is prevalent yet critical for designing heterogeneous catalysts; unfortunately, this effect rapidly decays in regions away from the interface, and it is always coupled with structural changes, bringing great challenges when optimizing the catalytic performance. Here, a reversible Cu(II/I) transition in a single-site Cu catalyst initiated by photo-doping is proposed to regulate EMSI. It is found that electron-rich Cu sites at the interface can effectively stabilize the hydride intermediate, leading to an up to ∼20-fold increase in hydrogenation activity. Photo-induced interfacial doping will open versatile paths for designing heterogeneous catalysts for organic transformations.

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 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.

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.
