Abstract:
The adsorption and decomposition of methylamine on the surface of a pristine silicon-carbide nanotube (SiCNT) are investigated by density functional theory calculations. The adsorption energies of possible stable configurations and the activation energies for possible elementary reactions involved are obtained in the present study. The most favorable reaction channel that generates a hydrogen cyanide molecule and four hydrogen atoms is slightly endothermic; the energy barrier for the decomposition of the CH3NH2 molecule is about 45 kcal/mol. Since the activation energy for the side reaction that generates CH3 and NH2 fragments is relatively high, the generation of side products may be depressed by decreasing the temperature.

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.
