Usuage of Graphene Material in Gas-Sensor

This paper mainly introduced the character of graphene when it was empolyed as gas-sensing material in the gas-sensor. The fabrication methods of graphene, the construction characters of devices composed of graphene prepared with different methods, the gas detection with different types of sensors, and the princinpal defects of the sensors were discussed and analyzed. Some foundmental methods were also suggested to improve the performances of the sensors. Reffering the authors’ part works, it was pointed out that the method constructing composite with semiconductor represented one of main trends for the application of graphene in the gas-sensor field.
