Abstract

129Xe NMR spectra obtained from microporous solid mixtures such as NaY-Pt/NaY and NaY-Pt/Al2O3 have indicated that the NMR peak pattern can depend greatly on the mixing method.129Xe NMR can thus be a very simple and useful technique to probe the physical mixing state of many composite catalysts.
