摘要：

The adsorption of pyridine at an Ag (210) single-crystal electrode has been studied by cyclic voltammetry, differential capacity and chronocoulometry. The study of pyridine adsorption was done in a 50 mM KClO4 solution for concentrations of pyridine ranging from 0.5 to 30 mM. In the range of potentials explored, adsorption and maximum coverage of the silver surface were observed. At potentials close to the potential of zero charge, the pyridine molecules assumed a vertical orientation with the nitrogen atom facing the metal. The adsorption isotherms were determined for the (210) face of silver. The present results are compared with those obtained at Ag (110) and (311) electrodes (A. Hamelin, S. Morin, J. Richer and J. Lipkowski, J. Electroanal. Chem., 272 (1989) 241 and 285 (1990) 249).
