Description: 
Layered Double Hydroxides nanostructures and their possibility of accommodating different molecules or atoms inside their matrix bestow a large number of interesting physical and chemical properties. Indeed, these materials have been widely used for different purposes. Nevertheless, their usage in gas sensors applications is still challenging since Layered Double Hydroxides conduction mechanisms are not completely clear. To this purpose, ac impedance spectrum analysis can represent a powerful technique to investigate specific conduction mechanisms. In fact, ac characterization allows highlighting the different contributions of the conduction and it permits to find out information about the undergoing physical phenomena. In this work, a fully ac characterization of a Nitrate-intercalated Zn/Al Layered Double Hydroxides gas sensor such as is performed. In particular, the complex impedance of the sensor is …
