Abstract
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.
