On the graphical analysis of the impedance response of passive electrodes

Mai T.T. Tran, Oumaïma Gharbi, Mark E Orazem, Bernard Tribollet, Mireille Turmine, Vincent Vivier

The analysis of the capacitive behavior of a passive electrode is often a difficult subject because the response obtained by electrochemical impedance spectroscopy (EIS) is characterized by a non-ideal behavior that we try to model by using a constant phase element (CPE) [1, 2]. In doing so, both…

Optimization of ammonium fluoride route to hierarchical ZSM-5 zeolites

T. Onfroy, Z. Qin, S. Casale, V. Valtchev

Preparation of hierarchical zeolites via a chemical etching is a hot topic as it strongly improves microporous material's diffusive properties and thus their catalytic activity. However, an issue that is often neglected is the softening the post-treatment condition. Herein we we report the…
