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.
