A study of the properties of ethylene on unpromoted and promoted silver catalyst by solid state nuclear magnetic resonance spectroscopy.

摘要

In this research, the properties of ethylene on unpromoted and promoted Ag catalyst were studied by solid-state nuclear magnetic resonance spectroscopy.;In Chapter one, the static cross-polarization spectra of ethylene at different temperatures were measured. Different jump site models are proposed to simulate the experimental results. The 3 site and 4 site jump models are chosen as the most satisfactory model to fit experimental spectra.;In Chapter two, the oxidation of ethylene over silver catalysts has been studied in detail by solid-state ;In Chapter three, the effects of a Cs;In Chapter four, the properties of Rb;In Chapter five, the interaction between silver metal and different forms of alumina has been studied by
