The review presents some key results of infrared investigations of adsorbents and catalysts, which were obtained in Laboratory of Adsorption and Catalysis at Adam Mickiewicz University – conducted under the author guidance. After short introduction, review is divided into seven parts. In the first chapter, there was described an application of infrared method devoted to examination of structure of different types of zeolites, such as A, X, Y and mordenite as well as alumina and fly ashes and their modifications. Moreover, some results were presented on cobalt–molybdena catalysts supported on alumina. In the next chapter chemisorption of pyridine and t-butylnitrile (TBN) molecules on the alumina and alumina modified with fluoride and sodium ions as well as Co(Ni)-Mo(W) catalysts supported on alumina were investigated. In the last case intensity of some spectra were correlated with catalytic activity for cumene cracking. Another set of experiments were devoted to transesterification on dealuminated mordenites containing cations of alkaline earths elements and correlation with infrared results. In the next part of review, chemisorption of ethanol was presented. It was concluded, that during chemisorption of ethanol different surface species were produced on alumina, silicaalumina and zeolites X and ZSM-5. In separate chapter, it was considered oligomerization of different alkenes on Phillips catalyst using IR methods. In the last chapter, ways of chemisorption of dihydrobenzenes on cobalt-molybdena catalyst were examined using IR reflectance spectra. It seems that above presented results based on infrared examination will help to better understand adsorbents and catalysts structure and their action during adsorption and catalytic reactions.
