In situ scanning FTIR microscopy and IR imaging of Pt electrode surface towards CO adsorption

In situ scanning FTIR microscopy was built up for the first time in the pre sent work, which consists of an FTIR apparatus, an IR microscope, an X-Y ma pping stage, and the specially designed electrochemical IR cell and compute r software. It has been demonstrated that this new space-resolvd in situ IR technique can be used to study vibration properties of micro-area, and to perform IR imaging of electrode surface. The chemical image obtained using this technique for CO adsorption on Pt electrode illustrated, at a space-re solution of 10(-2) cm, the inhomogeneity and the distribution of reactivity of micro-area of electrode surface.
