Zastosowanie spektroskopii w podczerwieni w adsorpcji i katalizie (II)
Journal Title: Wiadomości Chemiczne - Year 2011, Vol 65, Issue 5
Abstract
The review presents important results on infrared examination of adsorbents and catalysts, which were obtained in Laboratory of Adsorption and Catalysis in Environmental Protection at Adam Mickiewicz University – conducted under the author guidance. In the first chapter results on chemisorption of carbon monoxide on Pt and Pt–Sn catalysts supported on various carriers such as alumina with different specific surface area and silica were described. For these catalysts different amount of Pt or Pt and Sn were used. Besides, catalysts obtained by different preparation procedures were also investigated. Second chapter contains description of coke deposit on alumina and silica supports as well as on Pt and Pt–Sn catalysts supported on above mentioned carriers. Special attention was also devoted to coke deposition on aluminosilicate, zeolite type A, X and ZSM-5 and Pt–Cr, Pt-Mo and Pt-W catalysts supported on alumina. Moreover, coke deposition on alumina contained chloride ions and molybdena- (VI) ions on alumina activated by reduction and sulfidation were also investigated. It seems that above presented results based on infrared examination will help to better understand of adsorbents and catalysts structure and their action during adsorption and catalytic reactions.
