Abstract

An array of platinum microelectrodes was designed and fabricated. The adsorption of CO on such a Pt microelectrode (μ-Pt) was investigated by employing microscopein situ FTIR spectroscopy. A nanostructured film is formed at the surface of μ-Pt (denoted as μ-Pt(R)) when it has been subjected to a treatment of fast potential cycling. Abnormal infrared effects (AIREs) were observed in CO adsorption on the surface of μ-Pt(R), consisting of the inversion of the IR bipolar CO band and the extensively enhanced IR adsorption of COad species.
