Abstract

In the field of research on the detection of various harmful gases, nano-semiconductor metal oxide gas sensors hold a very important position. As an n-type semiconductor metal oxide, tungsten oxide has become a research focus and hotspot in gas-sensitive materials in recent years due to its unique structural and performance characteristics. This paper briefly introduces the gas-sensing response mechanism of tungsten oxide-based gas-sensitive materials, summarizes the main processes and directions for improving the gas-sensing performance of nano-tungsten oxide materials in recent years, and finally points out its own shortcomings and future research and development directions.
