| 中文摘要: |
| 本文在石墨烯改性碳纤维的基础上,通过添加聚偏氟乙烯(PVDF)造孔、浸渍法、水热法制备出不同的Pt-SnO2/改性碳纤维阳极催化剂。以扫描电镜(SEM)、X射线衍射仪(XRD)、拉曼光谱图、电催化性能、单电池发电性能等手段来表征和测试,结果表明添加PVDF造孔后催化剂催化性能最好,峰电流密度可达137.33mA.cm-2,其电阻也明显减少,当制备成单电池时也具有最高功率密度,为22.89 mW.cm-2。 |
| 英文摘要: |
| Based on the modified carbon fiber of graphene, different Pt-SnO2/ modified carbon fiber anode catalysts were prepared by adding poly vinylidene fluoride (PVDF), impregnating method and hydrothermal method. The physical and chemical properties of the cathode catalysts were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), raman spectra, electric catalytic properties, single battery power performance and so on. The results showed that after adding PVDF pore-forming catalytic performance is best, the peak current density of 137.33mA·cm-2, its resistance also decreased significantly, when preparation into a single battery also has the highest power density of the four methods, 22.89 mW·cm-2. |
