Mesoporous organo-inorganic hybrid materials as hydrogenation catalysts

The paper concerns application of two types of organic materials porous aromatic frameworks (PAFs) with diamond-like structure and the ordered mesoporous phenol-formaldehyde polymers (MPFs) - as supports for metal and metal sulfide nanoparticles. The obtained hybrid materials were tested in hydrogenation of various unsaturated and aromatic compounds. Ruthenium catalyst, based on PAF (Ru-PAF-30), possessed high activity in exhaustive hydrogenation of phenol into cyclohexanol with TOF value of 2700 h(-1). Platinum catalyst, based on modified with sulfo-groups MPF (MPF-SO3H-Pt), was selective in semi-hydrogenation of terpenes, [alpha-terpinene, gamma-terpinene, terpinolene, (s)-limonene]. Bimetallic Ni-W sulfide catalysts, prepared by in situ decomposition of [(n-Bu)(4)N](2)Ni(WS4)(2) within the pores of MPFs and PAFs, possessed high efficiency in hydrogenation-hydrocracking of naphthalenes as model substrates.
