QCM modified with FAU zeolite nanostructures for analysis of temperature induced adsorbed mass changes

Abstract:

In this work, the integration of various elements was realized. This allowed the development of a measurement system for quantitative determination of the electrical response of the faujasite-modified QCM, which was caused by a change in mass during the adsorption and desorption processes. The nanostructured faujasite film was grown on the QCM surface, and water was used as a ”model molecule” to test the ability of a measurement system to determine the change in mass associated with adsorption and desorption. It was shown that the sensitivity of the system is equal to 17 ng/Hz. The obtained sensitivity is sufficient to observe not only the adsorption and desorption process but even climate changes in the surrounding atmosphere.
