제목 | Highly Active and Stable CNT-TiO2 composite support for PEMFCs cathode catalyst |
초록 | Recently, some researchers have focused on the oxide support as promising materials due to their mechanical strength and sufficiently stability in acidic and oxidizing atmosphere. In these alternative material candidates, TiO2 support shows an excellent durability under PEM operation condition. In addition, it has a strong mutual attractive force with the Pt particles, the Pt can be strongly adhered on the surface of the support. Which means that the platinum dissolution issue can be alleviated. However, the electrical conductivity is considerably low that it requires certain modifications. In order to improve these drawbacks, composite catalyst was designed. In this morphology, platinum particles are embedded on the TiO2 support, and the electrons can be transported along the CNTs on the surface of the fiber. Due to the inherent stability of TiO2 and SMSI effect of the materials, the CNT-Pt/TiO2 can exhibited superior durability and activity. |
