Researchers report one-step fabrication method for rGO-based anodes for alkaline oxygen evolution reaction

Both MCO and rGO were formed on a porous Ni foam through a wet chemical process, via oxidation of the spinel phase and the simultaneous thermal reduction of graphene oxide (GO) in an air atmosphere at 300 °C. The (electro)catalytic properties of the MCO-based electrodes were studied in an alkaline medium (1 M KOH) to evaluate the impact of rGO on various OER activity parameters, in controlled amounts of 10 wt% and 20 wt% GO.

Researchers from Brazil’s Federal University of Paraíba – UFPB and Portugals’ University of Aveiro and LASI (Intelligent Systems Associate Laboratory) have presented a simple and cost-effective approach for the one-step synthesis of MnCo2O4-reduced graphene oxide (MCO-rGO) for use as an anode material in the oxygen evolution reaction (OER). Both MCO and rGO were formed on a porous Ni foam through a wet chemical process, via oxidation of the spinel phase and the simultaneous thermal reduction of graphene oxide (GO) in an air atmosphere at 300 °C.
