摘要
The present invention relates to a clean preparation method of a graphene-palladium nanocomposite, which comprises the steps of: (a) preparing graphene oxide; (b) reducing the graphene oxide; (c) adding reduced graphene oxide and a palladium precursor to a reactor and preparing a mixture in presence of supercritical carbon dioxide; and (d) obtaining graphene oxide of which the mixture is reduced with palladium by reducing pressure of the reactor and injecting hydrogen into the reactor. Further, the preparation method of the present invention does not produce byproducts unnecessary in manufacturing a palladium-based catalyst which can be used to Suzuki cross-coupling reaction, and excludes a separate process for removing an organic solvent, thereby being environment-friendly while remarkably reducing costs of manufacturing the catalyst.
