Volatile organic compounds (VOCs) are the major air pollutants inside vehicles. In this research, a highly sensitive gas sensor was developed based on an excellent sensing material and explored for VOCs sensing application. The X-ray diffraction and scanning electron microscopy were performed to evaluate the detailed structural features of sensing material. From the gas-sensing property tests to the three representative VOCs vapors, containing xylene, toluene and formaldehyde, the gas sensor fabricated from the exceptional sensing material significantly responses to the three VOCs vapors. In particular, the xylene response of the sensor is slightly larger than the other two gas response. Thus, the fabricated sensor could be a promising application for VOCs detection inside vehicles.
