NOVELTY - Preparing graphene noble metal composite slurry, comprises (a) mixing graphene oxide, noble metal inorganic salt and sodium oleate in water and ethanol, adding non-polar solvent to stir, heating, reacting under reflux condition, incubating solution, heating upper oil phase liquid to remove organic solvent, vacuum drying to obtain viscous graphene oxide/noble metal organic salt precursor, (b) heating the precursor under the inert atmosphere with organic solvent and dissolving to uniformly disperse, transferring the organic solvent to a high temperature reaction kettle, heating and reacting, cooling, adding cleaning agent to wash and centrifuging, discarding the upper layer liquid and obtaining the graphene noble metal composite particle, and (c) dispersing the composite particle in organic matrix according to requirement to obtain the required graphene noble metal composite slurry. USE - The method is useful for preparing graphene noble metal composite slurry. ADVANTAGE - The method is environment-friendly and has simple operation with low cost, thus suitable for large scale production, and utilizes non-toxic high temperature organic solvent in graphene oxide reduction process, thus avoids the use of the toxic and harmful substances e.g. hydrazine hydrate in the conventional reduction process.
