▎ 摘　　要

NOVELTY - The device has a reaction chamber (1), a cooling device (2), a high voltage electrode (3), a ground electrode (4), a temperature sensor (5), a pH sensor, a ground wire, a high voltage probe, a current coil, a high voltage power output line, a high voltage power supply, a power ground line and a power controller. The voltage output end of the high voltage pulse power supply is connected to the high voltage electrode of the reaction chamber. The ground electrode is connected to the ground wire. The high-voltage probe is connected at the high-voltage electrode. The ground wire is passed through the induction current coil. The input power is provided in the reaction chamber in time. The different parameters can be controlled by adjusting the high-voltage power control panel. A quartz tube is sheathed outside the electrode to prevent the electrode from reacting with the mixed solution. USE - Device for preparing noble metal/graphene composite nanomaterial. ADVANTAGE - The reaction efficiency is improved, and under the action of arc discharge, the precious metal nano particles on the composite material matrix are more uniformly distributed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the noble metal/graphene composite nanomaterial. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural diagram of the device for preparing noble metal/graphene composite nanomaterial.
