摘要：
Voltammetric measurement of the oxidative adsorption of 14 anions at Ag(111) is reported. The AE(111) electrodes are prepared by thermal deposition of Ag onto mica, followed by extensive thermal annealing in vacuum to produce clean, atomically-smooth, (111)-oriented surfaces. These electrodes display unusually well-resolved voltammetric responses towards anion adsorption. Typical cyclic voltammetric responses in aqueous solutions containing halides (F-, Cl-, Br-, I-), hydrosulfide and thiolates (CnH2n+1S-, n = 0, 2, 6), and oxyanions (OH-, CO3-2, C2H3O2-, SO4-2, NO3-, H2PO4-, B4O7-2) are presented and discussed in relation to previously published reports documenting anion adsorption at Ag(111).
