Rh-ions and Rh-complexes intercalated in γ-titanium or γ-zirconium hydrogen phosphate as highly efficient catalysts for arene hydrogenation

Monocyclic arenes are efficiently hydrogenated to their corresponding aliphatic hydrocarbons under relatively mild condition (T = 393 K, pH2 = 1-4 MPa) using Rh(III) ions or Rh(III) N,N′-complexes (N,N′ = 2,2′-bipyridyl, 1,10-phenanthroline) intercalated into γ-titanium or zirconium hydrogen phosphate.
