Nanostructured Metal Oxide Sensors for High-Performance Detection of Volatile Organic Compounds in Industrial Safety Systems

Abstract

The detection of volatile organic compounds (VOCs) in industrial environments is critical for ensuring workplace safety and environmental protection. Traditional gas sensors often suffer from low sensitivity, selectivity, and stability. Nanostructured metal oxide (MOX) sensors have emerged as a promising solution due to their high surface-to-volume ratio, tunable electronic properties, and enhanced gas-sensing performance. This paper explores the recent advancements in nanostructured MOX sensors for VOC detection, particularly in the context of industrial safety systems. Various synthesis techniques, sensing mechanisms, and material optimizations are discussed. The review highlights recent literature from 2023, providing insight into the latest developments in this field. Furthermore, experimental data, comparative performance analysis, and potential challenges are examined to guide future research directions.
