Synthesis of nanosized zeolites for VOCs detection

Abstract

Detection of volatile organic compounds (VOCs) is essential in many areas such as environmental monitoring, industrial safety and healthcare. Zeolites have recently emerged as promising microporous materials for gas sensing due to their unique properties including different pore sizes, shapes, large surface area, high adsorption capacity, excellent selectivity, and hydrophilic/hydrophobic characteristics. Our previous work has successfully demonstrated the deposition of zeolites onto sensor devices, followed by testing their reactivity on ethanol adsorption.
