Abstract
The hopping of protons in the anionic framework of zeolite H-ZSM5 with diff erent SiO2/Al2O3 ratios was examined by complex impedance spectroscopy. We found that the activation energy for the hopping process depends on the spa tial distance between the localization sites, given by the SiO2/Al2O3 ratio , according to classical hopping transport theory.
