NEW METAL-FREE CATALYSTS FOR THE SELECTIVE HYDROGENATION OF MULTIBLE BONDS İN AROMATİC HYDROCARBONS BASED ON GRAPHITIC CARBON NITRIDES
There has been demonstrated for the first time that polymeric carbon nitrides with graphitic structure can be successfully used as a metal-free catalyst for the selective hydrogenation of multiple bonds of aromatic compounds in vapor phase under atmospheric pressure of hydrogen. Graphitic carbon nitrides are capable to activate a hydrogen molecule and replace the metals for partial hydrogenation of phenylacetylene to styrene and phenol to cyclohexanone and cyclohexanol.
Keywords : graphitic carbon nitride, metal-free catalyst, phenylacetylene, phenol, hydrogenation, styrene, cyclohexanone, cyclohexanol
