Abstract

This study aimed to develop a gas sensor based on a ZnO-SnO₂ nanocomposite fabricated via ultrasonic chemical synthesis and to evaluate its ability to detect formaldehyde gas. The response, recovery, and selectivity of a series of sensors employing ZnO-SnO₂ nanocomposite samples produced using various synthesis energy levels were systematically evaluated. The experimental results revealed that the sensor using the ZnO-SnO₂ nanocomposite fabricated with a synthesis energy of 100,000 J produced the strongest response to formaldehyde gas and the fastest recovery time. It also demonstrated excellent selectivity when compared to toluene gas. These findings suggest that the use of an optimal synthesis energy can enhance the surface characteristics of ZnO-SnO₂ nanocomposites, thus improving their sensing performance.
