In the present work, palladium nanoparticles were synthesized in glycerol following the bottom-up methodology, using Pd(II) and Pd(0) precursors. The as-prepared materials were characterized by transmission electron microscopy (TEM) and powder X-ray diffraction (XRD), evidencing the formation of zero-valent palladium spheres in the nanosize ranges. The effects of metal precursors on the size of nanoparticles and their dispersion in medium reaction were illuminated, accompanying with the different catalytic activities towards C-N bond formation between acrylonitrile and morpholine. In particular, the recycling of catalytic phase was also desired thanks to immobilization of PdNPs in glycerol.
