Triuranium octoxide-reduced graphene oxide (U3O8/rGO) hybrids have been prepared by a two-step solution-phase method. The presence of GO is essential in order to obtain pure phase U3O8. The U3O8/rGO hybrids exhibited excellent electrocatalytic activity for the oxygen reduction reaction. The electron transfer number was calculated to be ~3.9 at –0.7 V (vs. Ag/AgCl) from the slope of the Koutecky–Levich plots. The U3O8/rGO hybrids were more stable than commercial Pt/C catalysts. Furthermore, when methanol was present, the U3O8/rGO hybrids still retained high activity. In addition, the U3O8/rGO hybrids can also catalyze the reduction of hydrogen peroxide.
