Diffuse Reflectance Infrared Spectroscopy DRIFT

Instrumentation. The interface within a suitably constructed electrochemical cell to be investigated is placed in the sample position of a standard DRIFT accessory for an infrared spectrometer for a typical design, see [328,329]. Examples reported so far deal with solid polymer electrolyte fuel cells where the surface of the anode layer exposed to a mixed gas atmosphere containing both water and methanol is separated from the environment via a Cap2 window [331, 332]. Various oxidized species and penetrating methanol were observed.

Several properties of the filler are important to the compounder (279). Properties that are frequentiy reported by fumed sihca manufacturers include the acidity of the filler, nitrogen adsorption, oil absorption, and particle size distribution (280,281). The adsorption techniques provide a measure of the surface area of the filler, whereas oil absorption is an indication of the stmcture of the filler (282). Measurement of the sdanol concentration is critical, and some techniques that are commonly used in the industry to estimate this parameter are the methyl red absorption and methanol wettabihty (273,274,277) tests. Other techniques include various spectroscopies, such as diffuse reflectance infrared spectroscopy (drift), inverse gas chromatography (igc), photoacoustic ir, nmr, Raman, and surface forces apparatus (277,283—290).

Generally speaking, the methods used to characterize carbonaceous material surfaces are referred to as wet and dry techniques. The former include potentiometric titrations and zeta potential or electrochemical methods the latter include temperature-programmed desorption (TPD) and spectroscopic methods such as x-ray photoelectron spectroscopy (XPS) and diffuse reflectance infrared spectroscopy (DRIFT). 

Showed that carbon in the surface or skin [12] consists of carbide (51%) carbon (41%) and carbonate (8%). Infrared depth profiling by diffuse reflectance infrared spectroscopy (DRIFT) provided further important insights [52], It showed that carbon alters the oxygen environment of the aluminum atoms near the fiber surface from octahedral to tetrahedral coordination and promotes the generation of carbonaceous species such as ethers and esters in addition to carbonates and carbides [52] which have also been found with XPS [12],...
