Abstract:
We report quasiclassical trajectory calculations of the H + HCO --> H(2) + CO reaction using a recent global potential energy surface. Three microscopic pathways are identified for this reaction. One is a direct abstraction, and the others both proceed via initial formation of a long-lived complex in the H(2)CO well followed by reaction (a) over the molecular saddle point transition state or (b) via a roaming pathway previously identified for the unimolecular photodissociation reaction [Townsend et al., Science 2004, 306, 1158]. Cross sections and product internal energy distributions for each pathway are calculated for five initial collision energies.

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.
