Infrared emission spectra from a heterogeneous catalyst system in reaction conditions 2: Infrared spectroscopic aspects

Abstract

Infrared spectroscopic aspects of IR emission investigations of a heterogeneous catalytic system in reaction conditions are outlined. A brief theoretical review of emission spectroscopy is given. In addition, experimental problems especially related to the microreactor designed for in situ IR emission investigations of catalytic reactions are discussed. It can be concluded that most experimental problems are not prohibitive. Infrared emission spectroscopy turns out to be a feasible technique over both a wide frequency range and a large temperature range. This is illustrated by a few experimental results.
