Infrared studies of species adsorbed in zeolites

Abstract

The work described in this thesis is concerned with the investigation of the infrared study of zeolites and species adsorbed on zeolites. In the first three chapters there are accounts on the zeolites structure and chemistry as well as the instrumentation and techniques which have been used. In the fourth chapter a study of the formation of coke on CaY zeolite and the various factors which influence its presence on the zeolite is reported. Chapter five is concerned with the presence of the hydronium ion formed by adsorbing water vapour on zeolites. Mn 4A zeolite can form the hydronium ion, while Co-4A does not. Finally, in chapter six, we report a study of cyclopropane gas adsorbed on Mn(II) and Co(II) partially exchanged A zeolites.
