The present project aims to investigate the thermal stability and dehydration/rehydration kinetics of four crystalline microporous hybrid organic-inorganic metallosilicates (Al-ECS-17, Ga-ECS-17, ECS-14 and Al-ECS-22, respectively) belonging to the class of Eni Carbon Silicates (ECS). The ECSs features strongly suggests that these hybrid materials is attractive for applications in the field of chemical sensors and catalysis. To our knowledge, to date no information are reported about the response to heating of AlECS-22 and ECS-14.

The aim of this work is to highlight the dehydration/rehydration kinetics of selected ECSs materials in order to highlight both structural and thermal stability as well as the flexibility in order to give more information about their functionality under operating conditions.

Abstract

The present project aims to investigate the thermal stability and dehydration/rehydration kinetics of four crystalline microporous hybrid organic-inorganic metallosilicates (Al-ECS-17, Ga-ECS-17, ECS-14 and Al-ECS-22, respectively) belonging to the class of Eni Carbon Silicates (ECS). The ECSs features strongly suggests that these hybrid materials is attractive for applications in the field of chemical sensors and catalysis. To our knowledge, to date no information are reported about the response to heating of AlECS-22 and ECS-14. The structural characterization of thermal behaviour of the above microporous hybrid metallosilicates becomes much relevant to predict and optimize the working conditions of each different material in the above applications. Furthermore, the rehydration dynamics strongly affects both the sensing and the diffusion properties. The aim of this work is to highlight the dehydration/rehydration kinetics of selected ECSs materials in order to highlight both structural and thermal stability as well as the flexibility in order to give more information about their functionality under operating conditions.
