Abstract:
Oxide-oxide interaction plays a vital role in regulating the electronic structure of supported metal in the oxide-supported metal catalysts, thereby strongly relating to CO2 hydrogenation efficiency. Although oxide-oxide interface offers a potential way to tailor metal-Ov synergy for boosting CO2 hydrogenation, its specific effects on the distribution of metal in different states are still ambiguous. Herein, we engineer a CeO2-Y2O3 interface to modulate Ov formation and electronic features of supported Cu nanoparticles. The CeO2-Y2O3 interaction also facilitates charge transfer and tunes adsorption behavior. The catalyst with the highest Cu+ species and a considerable amount of Ov achieves the intensified Cu+-Ov synergy, exhibiting a superior activity and catalyst stability for the reverse water-gas shift reaction. The present work provides a feasible strategy to trigger metal‑oxygen vacancy synergy for boosting CO2 hydrogenation reactions.

Heterogeneous Catalysis
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.
The hydrogenation process takes place on the...
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.
