Abstract: This article mainly introduces the significant harm of NO2 to the environment and human health, the importance of monitoring the concentration of NO2 in the environment, the research status and sensitive mechanism of the development of NO2 gas metal oxide sensitive devices in recent years, from the importance of detecting NO2 gas, the sensors sensitivity mechanism, sensing material, sensitivity, selectivity, detection limit and other aspects are summarized. The three aspects of noble metal doped metal oxides, sensitive materials with different morphologies and composite nanomaterials are actively studied to improve the sensitivity performance.The significance, combined with the actual needs of production and life, prospects the research and development direction of  NO2 metal oxide gas sensors.
Key words: NO2; metal oxide; gas sensor
