Ruthenium- and Palladium-Containing Catalysts Based on Mesoporous Polymer Nanospheres in Guaiacol Hydrogenation

Abstract

Catalysts Pd-NSMR and Ru-NSMR based on palladium and ruthenium nanoparticles deposited on a nanospherical mesoporous resorcinol-formaldehyde polymer are synthesized. It is shown that the average size of polymer particles is 220–250 nm and the average size of palladium and ruthenium nanoparticles is 7.2 and 2.2 nm, respectively. The catalysts are tested in guaiacol hydrogenation at a temperature of 200°С and a hydrogen pressure of 4.0 MPa. It is demonstrated that the ruthenium catalyst shows higher activity in guaiacol hydrogenation.
