Paper Abstract

There are many problems in the chemistry of solids which can be solved by "in situ" high temperature IR spectra measurement. Such a measurements should be very helpful in the studies of: phase transition, formation and decomposition of solids, adsorption on solid surfaces, oxidation or reduction reaction, to name a few. Among sampling techniques used in IR spectroscopy the transmission, diffuse reflection and emission seems be useful for high temperature IR spectra measurement. The main aim of the presented paper is to show the great potential of DRIFT technique in high temperature spectra measurements under controled atmosphere. The paper also show how DRIFT accessory can be used for IR emission spectra measurements as well. The following problems solved with high temperature DRIFT technique will be discussed in the paper: - Si02 polymorphic transition - desorption of the water molecules from quartz surface, - molybdenium and vanadium oxides reduction, - phosphor - molybdenium heteropolyacid catalyst reactions. Some experimental problems concerning the high temperature DRIFT measurements will be discussed also.
