The study presents the preparation and evaluation of ruthenium nanoparticles supported on multi-walled carbon nanotubes (RuL-MWCNT) for their catalytic efficiency in hydrogenation reactions. The nanoparticles were synthesized using a ligand stabilization method and characterized by elemental analysis and transmission electronic microscopy. The catalytic performance of the supported RuL-MWCNT was compared with non-supported ruthenium nanoparticles and ruthenium nanoparticles supported on other materials like silica, alumina, and activated carbon. The study found that the RuL-MWCNT catalyst demonstrated superior activity and selectivity in converting various unsaturated substrates to fully hydrogenated products, maintaining its catalytic behavior even after recycling. The support's nature significantly influenced the catalytic activity, with MWCNT showing the best results among the tested supports. The study concludes that the RuL-MWCNT system is an effective catalyst for hydrogenation processes, offering high activity, selectivity, and recyclability.
