제목 Electrochemical properties of Pt/nitrogen doped graphene intercalated by carbon black and its application in PEMFC
초록 Nitrogen is introduced to graphene as a dopant by pyrolytic synthesis of graphene oxide. Urea and graphene oxide are mixed and thermally reduced at 700 ℃. Nitrogen doped graphene [N-Gr] is used as a support for Pt nanoparticles. Pt/N-Gr is synthesized by microwave assisted method. Membrane electrolyte assemblies (MEA) are fabricated with commercial Pt/C as an anode catalyst and Pt/N-Gr as a cathode catalyst, respectively. Carbon black [CB] is intercalated to prevent graphene sheets from restacking. The intercalation ratio in Pt/N-Gr to CB is 6:4, 7:3 and 8:2, respectively. N-Gr and Pt/N-Gr are characterized by XRD, FT-IR, Raman spectroscopy, TG/DTA, SEM and TEM. Pt/N-Gr is electrochemically characterized by CV for measuring ECSA. MEA is characterized by cell performance test and OCV test.
