The introduction of Fourier Transform Infrared Spectroscopy (FTIR) brought along a number of typical solid sample techniques. DRIFTS (Diffuse Reflectance Fourier Transform Infrared Spectroscopy) is probably most commonly known. Another technique, developed specifically for measuring solid, opaque samples is PAS (Photo Acoustic Spectroscopy). This accessory is less known, probably due to its high cost and its rather difficult modus operandi. [Pg.491]

Using diffuse reflectance Fourier transform infrared spectroscopy, Adhikari et al. studied the binding of oleic acid (88), triacylglycerol (89), and phosphatidylcholine (90) on silica gel at room temperature. Their interpretation was that oleic acid and triacylglycerols bind to silica surface hydroxyls via hydrogen bonding interactions between the carboxylate and ester carbonyls of these molecules, respectively. In contrast, phospholipids hydrogen bond to silica surface hydroxyls via the phosphate... [Pg.2713]

Variable-temperature diffuse reflectance Fourier transform infrared spectroscopy provided qualitative and quantitative information concerning the acidity of surface sites on silica. Although the use of pyridine as a probe has been well known for many years, the ability of the technique to permit... [Pg.262]

Both chemical and physical processes take place during calcination and activation. Ligand decomposition from the metal complex can be monitored with in situ vibrational spectroscopy, for example, using diffuse reflectance Fourier transform infrared spectroscopy (DRIFTS). In the case of a transition metal ion, the metal oxidation state can be tracked as a function of time and temperature using in situ UV-vis spectroscopy. Finally, the formation of metal clusters and nanoparticles can be monitored using XRD, similar to that described for the synthesis of silicalite-1. [Pg.377]

The second group of techniques are the spectroscopic techniques that provide elemental and chemical analysis. These are diffuse reflectance Fourier transform infrared spectroscopy (DRIFTS), XPS, and SIMS. XPS and SIMS probe the first few nanometres of the surface whereas DRIFTS probes an order of magnitude deeper. These techniques are discussed in Section 3.5. [Pg.108]

SAMs of allgrlphosphonic acids (butylphosphonic acid, octylphosphonic acid, undecylphosphonic acid and octadecylphosphonic acid) on native niekel oxide allow substrates to be functionalized easily. Monolayer formation has been investigated by diffuse reflectance Fourier transform infrared spectroscopy, non-contact mode atomic force microscopy, contact angle measurements and matrix-assisted laser desorption ionization mass spectrometry. Cyclic voltammetry and electrochemical impedance spectroscopy studies showed that the monolayer increased surface resistance to oxidation. [Pg.291]

Most of the electrospinning procedures that yield metal oxide nanofibers involve pyrolysis of a guide polymer as a final processing step. Bender and co-workers demonstrated, using diffuse reflectance Fourier transform infrared spectroscopy (DRIFTS), that CO2 is sequestered in electrospun metal oxide nanofibers upon... [Pg.259]
