Fourier transform infrared (FTIR) spectroscopy is frequently used to characterize properties of catalytic sites, identify reaction intermediates, and probe interactions between adsorbates and surfaces, making it a versatile tool for elucidating reaction mechanisms in heterogeneous catalysis. While this technique is typically regarded as qualitative or semiquantitative in nature, quantitative results...
Liquid phase catalyst characterization is experimentally challenging, but it deserves consideration because solvent choice can affect catalyst structure and acidity. Thus, in vacuo spectroscopy of adsorbed probe molecules such as pyridine, while valuable, may provide incomplete information on available catalytic sites in liquid phase reactions. To this end, an Attenuated Total Reflection Fourier Transform...
