Abstract
We synthesized graphene-Pd nanocomposites in one-pot by ultrasound, radiation and liquid phase
plasma. Graphene dispersion containing Pd ions and 2-propanol was irradiated with ultrasound (200 kHz, 200
W) for 30 min and with gamma-ray (̴1 MeV) and electron beam (̴6 MeV). In radiochemical synthesis, the
absorbed dose was 10 kGy. In these processes, the reduction of Pd ions and oxidation of graphene occurred
simultaneously in one-pot. In the liquid plasma method, Pd nanoparticles generated directly from the
electrodes were deposited onto carbonyl modified graphene. Based on the results, the formation mechanism of
the nanocomposites was discussed.
