Gel-type resin with diamine functional groups, FCN, was used as a matrix for immobilization of ruthenium complexes. By reacting of RuCl3 with swollen matrix of FCN polymer a series of Ru/FCN composites with various Ru loading (1%, 2%, and 4%) was prepared All the characterization techniques (FT-IR, XRD, SEM, EDS, STEM, XPS, and DSC) proved the participation of functional groups in the coordination of Ru(III). These complexes contained both Cl- and N-ligands in various proportions depending on ruthenium loading in polymer Taking into account the chelating character of N-ligands a hypothetical structure of octahedral Ru(III) complex coordinated to FCN polymer was proposed. 2%Ru/FCN when reduced by NaBH4 exhibited catalytic activity in liquid phase hydrogenation of acetophenone. Higher selectivity in the presence of FCN supported Ru as compared to 2%Ru/Al2O3 catalyst toward 1-phenylethanol was observed. (C) 2010 Elsevier Ltd. All rights reserved.
