Abstract:
Low-loadings of Pt supported over six transition metal carbide (Pt/TMC) powder catalysts were synthesized and evaluated for hydrogen oxidation and evolution reactions in an alkaline electrolyte. The roughness factor of each Pt/TMC catalyst was different, indicating that the carbide supports affect the dispersion of Pt. Furthermore, when normalized by the corresponding roughness factors, all Pt/TMC catalysts were found to have similar intrinsic activities that were comparable to the state-of-the-art commercial Pt/C electrocatalysts.

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.
