Carbon nanatubes (CNTs) have potential applications in the selective and rapid detection of various gas species due to their special electrical, mechanical, physical, chemical performance . In recent years, researches on the application of CNTs in gas sensing have made a great progress. CNTs-based gas sensors enjoy many good features, such as small size, the capability of working at room temperature, high sensitivity, and short response time. This paper reviews the recent progress on the development of intrinsic CNTs-based gas sensors, the functionalization of CNTs-based gas sensors and the applications in human breath, with the focus on how to improve the sensing performance (sensitivity,selectivity ,response time and reproducibility) and increase the gas species of detecting through the rational functionalization of CNTs with different materials (organic polymers ,metals and metal oxides) .The new desorption method besides heating and ultraviolet radiation, the selective detection for specific gas in the complex surroundings, the technology of CNTs-based gas sensor arrays, and the implementation of commercial gas sensor devices will be issues for future reseaches.
