Article Synopsis
- Metal oxide nanowires (NWs) are promising for resistive gas sensors due to their high surface area, easy fabrication, and the ability to control their diameter and chemical composition.
- The vapor-liquid-solid (VLS) synthesis method is favored for its simplicity, cost-effectiveness, and the capability to create branched structures.
- The article reviews the growth and gas-sensing characteristics of various metal oxide NWs like SnO, ZnO, and CuO, focusing on how factors like catalyst type and growth temperature influence their performance.
This study addresses the concerns regarding the cross-sensitivity of metal oxide sensors by building an array of sensors and subsequently utilizing machine earning techniques to analyze the data from the sensor arrays. Sensors were built using InO Au-ZnO, Au-SnO, and Pt-SnO and they were operated simultaneously in the presence of 25 different concentrations of nitrogen dioxide (NO), carbon monoxide (CO), and their mixtures. To investigate the effects of humidity, experiments were conducted to detect 13 distinct CO and NO gas combinations in atmospheres with 40% and 90% relative humidity.
