Functionalized Graphene-Platinum Composites for Fuel Cells

The investigators plan to use a new material system they have recently developed to reduce dramatically the amount of expensive platinum needed in fuel cells. They can grow dispersed platinum nanoparticles on graphene, (one-atom thick sheets of carbon), without damaging the electrical or structural properties of the graphene. This may enable catalysis of key energy conversion reactions for fuel cells with high efficiency, in addition to reducing platinum use.
