Achieving the highly efficient hydrogenation of polycyclic aromatic hydrocarbons (PAHs) under mild temperatures remains a significant challenge. Herein, we report a highly active RuRh alloy catalyst supported on carbon nanofibers (RuRh/CNFs) developed via element screening. This catalyst achieves 100% conversion of naphthalene to decalin within 15 min at room temperature under solvent-free conditions. It exhibits a high turnover frequency (TOF) of 214.2 h-1 at 25 °C (1071 h-1 at 35 °C), significantly surpassing single-metal catalysts. Additionally, a 97% yield of the intermediate tetralin was obtained by fine-tuning the kinetic parameters. The catalyst demonstrates exceptional recyclability and broad substrate universality. Mechanistic studies attribute this performance to the synergistic effect between Ru and Rh, which enhances hydrogen migration and optimizes adsorption energies for substrates and intermediates, providing both theoretical insights and practical validation for the rational design of highly efficient PAHs as hydrogenation 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 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.
