摘要：

A kinetic study of the Ag electrodeposition onto Pt ultramicroelectrodes of 10, 15 and 25 mu m of diameter from an aqueous solution containing AgNO3 1 mM + NH4NO3 0.1 M was conducted at overpotential conditions through potentiostatic studies. The analysis of the current density transients indicates the existence of two 2D nucleation and growth processes previous to the 3D nucleation and growth process.
