NOVELTY - Preparation of three-dimensional graphene-loaded nano palladium catalyst by soft template comprises weighing 0.5-4 mg/ml graphite oxide, adding deionized water in an emulsion system of ethanol and cyclohexane, sonicating for 5-20 minutes at room temperature to obtain dispersed graphene oxide emulsion, adding 60-100 mg ascorbic acid to emulsion, treating mixture in water bath at 60-90 degrees C for 0.25-2 hours, adding 0.3-1 mL palladium chloride aqueous solution, mixing in oil bath, centrifuging mixture with deionized water, washing ethanol and drying. USE - Method of preparing three-dimensional graphene-loaded nano palladium catalyst by soft template used for reducing nitrobenzene to aniline (claimed). ADVANTAGE - The catalyst exhibits high catalytic activity and stability and has high recovery rate, mild preparation condition, simple process and low cost.
