Description: A nanometer palladium catalyst and preparation method for the hydrogenation of anthraquinone, involving a palladium catalyst. Provide nanometer palladium catalyst and preparation method of an anthraquinone hydrogenation using natural plant used as a reducing agent and a carrier. The nano-palladium catalyst by palladium nanoparticles dispersed on a carrier composed of gardenia, as a percentage by mass, palladium loading of 1.2% ~ 3.6% gardenia. The palladium nanoparticles size 3 ~ 10nm. Preparation Gardenia leachate: The gardenia with flooding, too gardenia leachate; Nano palladium catalysts: palladium chloride leaching solution paired with gardenia gardenia mixed solution of palladium chloride, after reduction and dried to obtain the load on Gardenia nano-palladium catalyst, palladium catalyst that is used in nano-anthraquinone hydrogenation.
