| 中文摘要 | a novel method for fabrication of nanometer-sized electrodes and tips suitable for scanning electrochemical microscopy (secm) is reported. a fine etched pt wire is coated with polyimide, which was produced by polymerization on the pt surface initiated by heat. this method can prepare electrodes with effective radii varying from a few to hundreds of nanometers. scanning electron microscopy, cyclic voltammetry, and secm were used to characterize these electrodes. well-defined steady-state voltammograms could be obtained in aqueous or in 1,2-dichloroethane solutions. ibis method produced the nanoelectrodes with exposed pit on the apex, and they can also be employed as the nanotips for secm investigations. different sizes of pt nanotips made by this method were employed to evaluate the kinetics of the redox reaction of ru(nh3)6(3+) on the surface of a large pt electrode by secm, and the standard rate constant kappa (o) of this system was calculated from the best fit of the secm approach curve. this result is similar to the values obtained by analysis of the obtained voltammetric data. |
