Synthesis and ​characterization of WO3–SnO2/rGO ​nanocomposite ​for Propan-2-ol ​sensing

Abstract

Volatile organic compounds (VOCs) are hazardous for both environment and human health. With increase in the usage of VOCs containing products, the extent of hazard is inceasing at an alarming rate. Therefore, the monitoring and sensing of VOCs become a need of the hour. Keeping in view, in the present work, We had studied the effect of rGO doping on the sensing performance of WO3–SnO2 ​mixed metal oxide for Propan-2-ol. The optical characterization of as-prepared samples were done using UV/Vis and FTIR spectroscopy. The structural and morphological analysis was studied using XRD and FESEM technique, respectively. The electrical studies were checked by I–V measurements. The sensing parameters such as sensitivity, response, recovery time, effect of temperature and concentrations, as well as stability were also studied. .
