Abstract

Polyvidone (PVP40)-stabilized Rh nanoparticles (Rh@PVP40) were synthesized via a classical alcohol reduction technique and were characterized by carrying out TEM, HR-TEM, TEM/EDX, P-XRD analysis, UV/Vis and XPS spectroscopy investigations. Approximately, non-touch each other 100 particles in were counted TEM image in 50 nm scale and the average particle size of Rh@PVP40 nanocatalyst was found to be 3.32 ± 0.26 nm. The prepared nanoparticles were found to be one of the most efficient catalytic systems in the literature, with a high TOF value (185.91 min−1) and low activation energy (43.88 kJ mol−1) for the hydrolytic dehydrogenation of a methylamine-borane compound. Analysis of the effects of catalyst and substrate concentrations on the catalytic reaction indicated that the reaction proceeded to the 1.37-order of the catalyst concentration and nearly zero order of the substrate concentration.
