Abstract
CO interacts with exchangeable cations M+ (gray spheres in the picture) of zeolites to form M+ ⋅⋅⋅CO and M+ ⋅⋅⋅OC species (C: black; O: white) which are in a temperature-dependent equilibrium. For Na-ZSM-5 (M+ =Na+ ) the difference in interaction energy amounts to 3.8 kJ mol-1 , as determined by means of variable-temperature FT-IR spectroscopy. © 1998 WILEY-VCH Verlag GmbH, Weinheim, Fed.
