Abstract

Design and fabrication of acetone sensor is essential as it has adverse effect on human health. This research proposes a novel acetone sensor applicable for ambient environment. A reduced graphene oxide and Zinc Oxide (rGO-ZnO) nanocomposite has been synthesised to induce the selectivity towards acetone. The proposed sensor has been characterised using electrochemical impedance spectroscopy (EIS) method for various acetone concentrations (10–300 ppb), temperature (5–55℃) and humidity (40–90%). The temperature and humidity effects have been compensated to make the applicable for actual environmental conditions. The response and recovery time is 4 s and 7 s, respectively. Moreover, the outcomes of the cross-sensitivity and repeatability tests are highly promising to use the sensor for various environmental and biomedical applications.
