Utilization of functionalized graphene and its nanocomposites as a catalyst support in fuel cells

The production of novel catalyst support materials could open up new ways in order to enhance the catalytic activity by reduced catalyst loading. At this point, nanocomposites composed of conducting polymers like polypyrrole (PPy) reinforced with GNS are being considered as catalyst support for fuel cell applications. In the present work, the effect of chemical properties of graphite oxide (GO) sheets, GNS and their nanocomposites on catalyst size, dispersion and surface chemistry was investigated in detail to fabricate novel catalyst support materials.
