Project Details


Graphene-supported, size-selected Pt-based nano-electrocatalysts for bendable fuel cell applications will be studied. From scientific viewpoint, we plan to investigate the electrochemical properties of graphene-supported, size-selected Pt-based electrocatalysts. It is reported that graphene-supported Pt catalysts (< 1 nm) exhibit excellent methanol-oxidation-reaction (MOR) activity but they can not avoid the existence of large catalysts through their process. (E. Yoo et al. Nano Lett. 2009, 9, 2255.) Therefore, we are going to synthesize the size-selected Pt-based electrocatalysts and explore their electrochemical properties. (C. Bock et al. J. Am. Chem. Soc. 2004, 126, 8028.) In brief, metal-support interaction and size effect of catalysts on graphene as the carbon support material are what we will discuss. From engineering viewpoint, we plan to integrate nano-electrocatalysts in bendable fuel cells. (S. Tominaka et al. Energy Environ. Sci. 2009, 2, 1074. Editor’s choice in Science, 325, 1321, 2009.) Through the collaboration with Waseda university, we will prepare the electrode with nano-electrocatalysts on flexible polymer substrate and study their electrochemical properties. On the other hand, we will use graphene electrode to replace the original thick and expensive Au electrode in their paper. With the help of appropriate nanomaterial process, we can not only improve the performance of bendable fuel cell but also lower down the cost. Besides our experience in carbon nanotubes, (C. L. Sun et al. Chem. Mater. 2005, 17, 3749 Citation > 60, IF = 5.046; J. Am. Chem. Soc. 2006, 128, 8368 IF = 8.091; J. Electrochem. Soc. 2009, 156, B1249.) we already have some preliminary results which prove this project is doable as well as valuable. It is believed that we must be able to contribute to the energy issue with significant research achievement and publications.
