In situ scanning FTIR microscopy and IR imaging of Pt electrode surface towards CO adsorption
- 化学化工－已发表论文 
In situ scanning FTIR microscopy was built up for the first time in the present work, which consists of an FTIR apparatus, an IR microscope, an X-Y mapping stage, and the specially designed electrochemical IR cell and computer 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-resolution of 10(-2) cm, the inhomogeneity and the distribution of reactivity of micro-area of electrode surface.
