Room-temperature SO2 gas sensing properties of the Ag@GO heterogeneous nanomaterial
Main Article Content
Abstract
The study proposes a SO2 gas sensor based on quartz crystal microbalance (QCM) using Ag@GO heterogeneous nanomaterial at room temperature. Heterogeneous nanomaterial were synthesized by hydrothermal method at 160 °C for 90 min. The material’s properties were characterized through measurement techniques, including field emission scanning electron microscope (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and Raman spectroscopy. Ag@GO heterogeneous nanomaterial which acted as SO2 adsorption layer, was dispersed in water and coated on an Au electrode of QCM via spray coating method. The manufactured sensor demonstrates good response to SO2 in the concentration range of 2.5–15 ppm. The sensor's highest gas sensitivity is 8.98 Hz/ppm corresponding to the adsorbed SO2 mass density of 2.379 μg·cm⁻². The research findings demonstrate that the manufactured sensor can be applied to such fields as monitoring, warning, and controlling SO2 in the environment. Ag@GO nanomaterial’ gas adsorption properties can be used as a filter to remove toxic gases in respirators and other fields relating to toxic gas emission.
