▎ 摘　　要

NOVELTY - A nanometal particles loaded graphene composite material preparing method involves oxidizing graphite by Hummers method to prepare graphite oxide. Water is added to the graphite oxide, after ultrasonic dispersion, to form uniformly dispersed graphene oxide solution. Metal nitrate powder is added into the graphene oxide solution and agitated. The obtained mixed solution is dried. The solvent is removed. The obtained powder is placed in inert gas atmosphere, pre-heated and cooled to room temperature. The cooled product is subjected to reduction reaction under reducing atmosphere and cooled. USE - Method for preparing nanometal particles loaded graphene composite material. ADVANTAGE - The method enables effectively preparing the nanometal particles loaded graphene composite material with high conductivity. DETAILED DESCRIPTION - A nanometal particles loaded graphene composite material preparing method involves oxidizing graphite by Hummers method to prepare graphite oxide. Water is added to the prepared graphite oxide, after ultrasonic dispersion, to form uniformly dispersed graphene oxide solution. Metal nitrate powder is added into the graphene oxide solution and agitated at room temperature to obtain evenly dispersed mixed solution. The mixed solution is dried. The solvent is removed to obtain powder. The powder is placed in an inert gas atmosphere, pre-heated and cooled to room temperature. The cooled product is subjected to reduction reaction under reducing atmosphere and cooled to room temperature, after the reaction is finished. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a method for preparing nanometal particles loaded graphene composite material.
