摘要

An array of platinum microelectrodes was de - signed and fabricated. The adsorption of CO on such a Pt microelectrode (μ-Pt) was investigated by employing micro - scope in 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 inver - Sion of the IR bipolar CO band and the extensively enhanced IR adsorption of CO_ad species.
