Bifunctional gold-manganese oxide nanocomposites: benign electrocatalysts toward water oxidation and oxygen reduction

摘要

Gold-manganese oxide nanocomposites were synthesised by seed-mediated epitaxial growth at the water-heptane interface under mild reflux conditions. These nanocomposites exhibit efficient electrocatalytic activity toward the water oxidation reaction (WOR) and the simultaneous oxygen reduction reaction (ORR) at a low overpotential (eta approximate to 370 mV) and under neutral pH conditions.
