AbstractDespite homogeneous catalysts are in general superior to heterogeneous catalysts in terms of activity and selectivity, their difficult separation from the products and subsequent reutilization is an important drawback that makes industries reluctant to use them in large scale processes. Currently 90 % of industrial catalytic processes make use of heterogeneous catalysts. For these reasons several efforts are being carried out for the immobilization of known and highly active homogeneous catalysts onto solid supports. In this regard we have recently reported the immobilization of ruthenium and palladium organometallic compounds onto graphene materials by p-stacking interactions. In this work, we have synthesized three Ru-NHC complexes bearing different aromatic fragments that allow the immobilization of the complexes onto reduced graphene oxide by non-covalent interactions (Scheme 1). The catalytic properties of the molecular complexes and the new hybrid-graphene materials have been studied in the oxidative dehydrogenation of primary alcohols in water. The results show that the hybrid materials improve the catalytic outcomes compared to the homogeneous complexes, and that the immobilization of the molecular entities onto reduced graphene oxide allows the recovery and reuse of the catalyst.
