Abstract
Formic acid electrooxidation over Pt deposited on two types of graphene supports are examined. The first support was prepared by rigorous chemical reduction of graphite oxide (GO) to form pure graphene (GCH). The second support is prepared by simultaneous reduction and functionalization of GO with ethylenediamine (GUE) by a one-step ultrasonication method. GUE show a significant shift in the HCOOH oxidation onset potential compared to GCH as well as other forms of commercial carbon supports. A comparative analysis of Pt activity towards formic acid electrooxidation over glassy carbon (GC) shows the following trend: Pt-GC-GUE>Pt-GC-GCH> HiSpec 3000 > Pt-GC-Vulcan XC-72.
