Abstract:
Large scale exploitation of shale gas has stimulated the developments of on-purpose propane dehydrogenation (PDH) technologies. Pt-based PDH catalysts have been utilized in industry, e.g. Pt-Sn/Al2O3 and Pt-Ga/ Al2O3, where the actual role of metal dopants is not fully understood. In this regard, the development of model systems possessing tailored surface sites is necessary in order to look into the structure-activity relationships. In that context, the surface organometallic chemistry (SOMC) approach has emerged as a powerful tool to yield PDH model catalysts, revealing that the formation of alloyed particles and residual unreduced metal sites are important for high productivity and stability.

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 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.
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...
