▎ 摘　　要

NOVELTY - Preparation of platinum-palladium nanocatalyst supported on graphene comprises mixing palladium and platinum in graphene oxidize ethanol dispersion liquid for 1-4 hours, dispersing ultrasonic for 0.5-2 hours, refluxing at 85-90 degrees C for 4-8 hours, concentrating and drying at 100-120 degrees C for 2-3.5 hours. USE - Method of preparing platinum-palladium nanocatalyst supported on graphene used for catalyzing the hydrogenation of boron hydride to produce hydrogen (claimed). ADVANTAGE - The nanocatalyst is simple and has high catalytic activity and strong durability.
