Single Potential Infrared SPAIRS

Reaction products can also be identified by in situ infrared reflectance spectroscopy (Fourier transform infrared reflectance spectroscopy, FTIRS) used as single potential alteration infrared reflectance spectroscopy (SPAIRS). This method is suitable not only for obtaining information on adsorbed products (see below), but also for observing infrared (IR) absorption bands due to the products immediately after their formation in the vicinity of the electrode surface. It is thus easy to follow the production of CO2 versus the oxidation potential and to compare the behavior of different electrocatalysts. [Pg.76]

Figure 11.10 Single potential alteration infrared (SPAIR) spectra of the species coming from ethanol adsorption and oxidation on a Pt-Sn (90 10)/C electrode (0.1 M HCIO4 + O.IM C2H5OH, 25 °C). The reference spectrum was taken at 50 mV vs. RHE.

In situ IR spectra were recorded using, either the Single Potential Alteration Iirfrared Reflectance Spectroscopy (SPAIRS), also called Linear Potential Sweep-Fourier Transform Infrared Reflectance Spectroscopy (LPS-FTIRS), or the Subtractively Normalized Interfacial Fourier Transform Infrared Reflectance Spectroscopy (SNIFTIRS). ... [Pg.400]

The same method is sometimes called PDIRS (for potential difference infrared spectoscopy) or SPAIRS (for single potential alteration infrared spectroscopy). [Pg.701]

Ag-coated Ge hemicylindrical prism with a 0.6 s data acquisition time by exploiting SEIRAS. Spectra were collected during the acquisition of a cyclic voltammogram, recorded at a scan rate of 10mVs this experimental protocol was earlier termed SPAIRS (single potential alteration infrared spectroscopy) by Weaver and coworkers [121] (see Sect. 3.5.4.1.3 in the following text). [Pg.549]
