Synthesis and Electrocatalysis of Carbon Nanofiber-Supported Platinum by 1-AP Functionalization and Polyol Processing Technique

Pt/carbon composite nanofibers were prepared by depositing Pt nanoparticles directly onto electrospun carbon nanofibers using a polyol processing technique. The morphology and size of Pt nanoparticles were controlled by 1-aminopyrene functionalization. The noncovalent functionalization of carbon nanofibers by 1-aminopyrene is simple and can be carried out tit ambient temperature Without damaging the integrity and electronic structure of the carbon nanofibers. The resulting Pt/carbon composite nanofibers were characterized by running Cyclic voltammograms in 0.5 M H2SO4 and 0.125 M CH3OH + 0.2 M H2SO4 Solutions. Results show that Pt/ carbon composite nanofibers with l-aminopyrene functionalization have Pt nanoparticles with a smaller size and better distribution Compared with those treated with conventional acids. Moreover, Pt/l-aminopyrene-functionalized carbon nanofibers possess the properties of high active Surface area, improved performance toward (fie electrocatalytic oxidation of methanol, and relatively good long-term stability.
