摘要:
The best-known quality of microelectrode is the low capacity of the interfacial double layer[1]. In this paper, we have designed specially and fabricated an array electrode of micro-Pt (μ-Pt). 16 μ-Pt (200μm in diameter) electrodes were arranged in a 4 x 4 array, and the distance between each neighboring μ-Pt is 200μm. The associating designed electronic board allows to connect any individual μ-Pt or collective μ-Pts by selection with potentiostat, so the properties of an individual μ-Pt or arbitrarily grouped μ-Pt can be investigated conveniently. Moreover, by employing the in situ FTIR Microscopy[2], the surface processes of CO adsorption on the array electrode were studied. Information at molecule level concerning the abnormal infrared effects (AIREs)[3] of individual μ-Pt subjected to a fast potential scan treatment and the interaction between μ-Pts (coupled action) have been obtained for the first time.
