▎ 摘　　要

NOVELTY - The preparation method of platinum nano particles loaded three-dimensional nitrogen-doped graphene aerogel involves preparing graphene oxide aqueous solution, and ultrasonically mixing chloroplatinic acid solution and prepared graphene oxide aqueous solution, adding glycine, ultrasonically dissolving to obtain mixed solution (A), adding the mixed solution (A) to the stainless steel high pressure kettle, burning, cooling to room temperature, leaving stand for 2 days, removing the un-reacted material by changing the water and repeatedly washing, and freeze-drying for 2 days. USE - Preparation of platinum nano particles loaded three-dimensional nitrogen-doped graphene aerogel (claimed). ADVANTAGE - The method enables preparation of platinum nano particles loaded three-dimensional nitrogen-doped graphene aerogel with excellent performance, catalytic properties and stability.
