The development of a stable and efficient Oxygen Reduction Reaction (ORR) electrocatalysts with high methanol tolerance is crucial for Direct Methanol Fuel Cells (DMFCs). Herein, triphenylphosphine (PPh3)-ligated gold nanoclusters complexes (AuNCs), Au101(PPh3)21Cl5, Au9(PPh3)8(NO3)3, Au1(PPh3)Cl supported on reduced graphene oxide (rGO) have been explored as tolerant ORR electrocatalysts.
