The hydrogenation of anthracene on a heterogeneous catalyst containing 3 wt % Pt/C (Aldrich) at 215, 245, and 280°C and the pressures of 40 and 90 atm is studied. The hydrogenation of anthracene to a completely hydrogenated product is considered in detail

Pt(0.5 wt %)-Al-SBA-15 and Pt(0.5 wt %)-Al-MCM-41 bifunctional catalysts were prepared by wet impregnation and investigated in the hydrogenation of anthracene and the hydrogenolysis/hydrogenation of a series of synthesized Diels-Alder adducts with anthracene and anthracene derivatives. The mesoporous texture of the investigated catalysts allowed the hydrogenation of these substrates to a large extent. In direct correlation with the size of the Pt particles, Pt-Al-SBA-15 exhibited a higher activity. Both catalysts exhibited a strong Lewis acidity associated with the presence of the Al extra-framework species. The acidity of these catalysts afforded the esterification of the reaction byproduct, that is, succinic anhydride, with methanol or ethanol, and the hydrocracking/decyclization of one hydrogenated ring to lead to 1,2,3,4-tetrahydronaphthalene derivatives. A good correlation with the calculated values of the reaction Gibbs free energy has been evidenced.
Facile sonochemical synthesis of carbon nanotube-supported bimetallic Pt-Rh nanoparticles for room temperature hydrogenation of arenes

Bimetallic Pt-Rh nanoparticles can be deposited uniformly on surfaces of carboxylate functionalized multi-walled carbon nanotubes (MWNTs) using a simple one-step sonochemical method. The bimetallic nanoparticle catalyst exhibits a strong synergistic effect relative to the individual Pt or Rh metal nanoparticles for catalytic hydrogenation of polycyclic aromatic hydrocarbons (PAHs), neat benzene and alkylbenzenes. Complete ring saturation of PAHs can be achieved using the bimetallic Pt-Rh/MWNTs catalyst at room temperature. This one-step synthesis technique provides a simple and rapid way of making highly active and recyclable CNT-supported monometallic and bimetallic nanocatalysts for low temperature hydrogenation reactions.
