Protonic conductivity of Pt/Al2O3 in hydrogen- and water-containing atmospheres
Source abstract
Abstract
Abstract Changes of electrical properties of a 0.5% Pt/Al2O3 catalyst and of γ-Al2O3 measured in situ during temperature programmed hydration/dehydration have been correlated with TG–DSC data, obtained in similar conditions. The results are explained in terms of hydrogen spillover to the support facilitated by the presence of traces of water (protonic conduction by “vehicle” mechanism).
