An infrared spectroscopic study of some carbonaceous materials

摘要: Abstract IR photothermal beam deflection spectroscopy (PBDS) was used to record spectra of intermediate-temperature carbon materials having greatly different properties and origins. A good charcoal, anthracite coal, bituminous two Chromatographic carbons were studied in a cell under the controlled conditions required for surface studies. PBD recorded after various heat treatments vacuum, oxidation, compared with those cellulose-derived chars. data concerning degree carbonication, formation changes species making up layers, inorganic within carbons, obtained easily are discussed. IR-PBDS is valuable technique study intermediate their reactions.
