In this work, Mo-MCM-41, Zr-MCM-41, Sn-MCM-41 and Ti-MCM-41 mesoporous molecular sieves were successfully synthesized via hydrothermal synthesis. An acidic group (SO42−, PTSA etc.) was introduced into the mesoporous molecular sieves to obtain modified mesoporous molecular sieve catalysts. The XRD, N2 absorption–desorption isotherms, FT-IR and Py-IR results reveal that PTSA/ZrO2/Mo-MCM-41 had a mesoporous...
Fe3O4@C supported ultrasmall and highly monodisperse ruthenium (Ru) nanoparticles (Ru/Fe3O4@C) were prepared as novel nanocatalysts for hydrogenation reactions. The catalysts displayed high activity for the hydrogenation of rosin to form hydrogenated rosin with extraordinary selectivity. The role of controlled carbon size on the catalytic properties of the catalysts was studied. The Ru/Fe3O4@C catalyst...
