Abstract: Ru nanoparticles (NPs) stabilized by polyvinylpyrrolidone (PVP) were synthesized and immobilized on mesoporous Sibunit, carbon nanofibers of platelet structure (CNF-Pl) and TiC carbide-derived carbon (CDC) providing 1.7÷2.9 wt.% Ru/C catalysts with the mean Ru size 2.1÷2.7 nm. The presence of PVP on the catalyst surface drastically diminished activity in structure sensitive galactose to galactitol hydrogenation. Different PVP removal and support modification methods were tested to elucidate the effect of support hydrophilicity/ hydrophobicity, preliminary support functionalization, additional Ru NPs washing prior to immobilization as well as PVP removal degree on catalytic behaviour. To characterize the carbon supports and synthesized catalysts TEM, XPS, XRD, XRF, water adsorption/desorption experiments and N2 physisorption were applied
