Abstract:
The hydrogenation of CO2 to synthesize liquid hydrocarbons (such as aromatics, gasoline, jet fuels, and diesel) is one of the important ways to achieve carbon cycling and sustainable fuel production. Spinel catalysts (AB2O4) have attracted increasing attention due to their flexible lattice structure, thermal stability, adjustable oxygen vacancies, and tunable metal-support interaction. However, most existing reviews focus on the static design of catalysts while neglecting the dynamic structural evolution of spinels under actual reaction conditions. This review systematically elaborates on the dynamic formation process of the active interface of spinel catalysts. By integrating in situ characterization with density functional theory (DFT) calculations, this study elucidates the nature of active sites and the reaction mechanism of spinel catalysts during CO2 hydrogenation to liquid hydrocarbons. Based on this, guided by the target product selection behavior, a series of precise construction strategies such as defect engineering, doping effects, interface engineering, and morphological structures were summarized to achieve efficient C─C coupling and liquid hydrocarbon generation. Finally, the current key challenges and future development directions were discussed, providing theoretical guidance for the development of efficient, low-energy-consuming, and industrially applicable spinel catalysts.

02:13Reduction 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.

02:24Reduction 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.
02:17Reduction 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...

The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...
