【 摘 要 】

Nanoelectrode arrays are much in demand in electroanalytical chemistry, electrocatalysis, and bioelectrochemistry. One of thepromising approaches for the preparation of such systems is templated electrodeposition. In the present study, porous anodicalumina templates are used to prepare Au nanoelectrode arrays. Multistage electrodeposition is proposed for the formation ofrecessed electrodes with the ability to tune the distance between the surface of the porous template and the top surface of the nanoelectrodes. A set of complementary techniques, including chronoamperometry, coulometry, and scanning electron microscopy, areused to characterize the nanoelectrode arrays. The number of active nanoelectrodes is experimentally measured. The pathways tofurther improve the recessed nanoelectrode arrays based on anodic alumina templates are discussed.
