▎ 摘  要

NOVELTY - A copper-platinum (Cu-Pt) alloy with trigonal bipyramidal (TB) and truncated cube (TC) (CuPt-TB-TC) mixed structure dispersed on nitrogen doped graphene surface is synthesized by dispersing nitrogen doped graphene in ethylene glycol by sonication for 5-6 hours at 25-30 degrees C, adding polyvinylpyrrolidone, chloroplatinic acid solution and copper chloride solution at 25-30 degrees C to obtain nitrogen doped graphene (NGr) ethylene glycol solution with metal precursor and surfactant, adding potassium iodide solution, stirring for 15 minutes at 25-30 degrees C, and heating at 140 degrees C for different time intervals. USE - Synthesis of copper-platinum (Cu-Pt) alloy with trigonal bipyramidal (TB) and truncated cube (TC) (CuPt-TB-TC) mixed structure used in fuel cell and metal air batteries (all claimed). ADVANTAGE - Copper-platinum (Cu-Pt) alloy with trigonal bipyramidal (TB) and truncated cube (TC) (CuPt-TB-TC) mixed structure dispersed on nitrogen doped graphene surface is highly active and stable and has outstanding ORR activity in alkaline condition. DETAILED DESCRIPTION - A copper-platinum (Cu-Pt) alloy with trigonal bipyramidal (TB) and truncated cube (TC) (CuPt-TB-TC) mixed structure dispersed on nitrogen doped graphene surface is synthesized by dispersing nitrogen doped graphene in ethylene glycol by sonication for 5-6 hours at 25-30 degrees C, adding polyvinylpyrrolidone, chloroplatinic acid solution and copper chloride solution at 25-30 degrees C to obtain nitrogen doped graphene (NGr) ethylene glycol solution with metal precursor and surfactant, adding potassium iodide solution to solution, stirring for 15 minutes at 25-30 degrees C, heating at 140 degrees C for different time intervals of 30, 60, 90 and 120 minutes and purifying to obtain desired CuPt/NGr samples labeled as CuPt-TBTC/NGr-30, CuPt-TBTC/NGr-60, CuPt-TBTC/NGr-90 and CuPt-TBTC/NGr-120, respectively.
