摘要：

Catalytic activity of a polycrystalline gold electrode toward oxygen reduction reaction (ORR) in aqueous alkaline media in the presence of various alkali-metal sulfates (M2SO4, M = Li, Na, K, Rb and Cs) was investigated by hydrodynamic voltammetry. The fraction of 4e(-) pathway in low overpotentials (-0.1 to -0.3 V) depended on the alkali-metal cations (Rb >> Na, K, Cs, Li). A complete 4e(-) reduction of O-2 was only attained in the presence of Rb+ cation in the solution, which was comparable or even superior to that reported at the Au(100) single crystal electrode.
