Gas Sensor Research Has Made New Progress

The Institute of Physical and Chemical Technology, Chinese Academy of Sciences researcher Junhui the functional nanomaterials research group leaders using nano-structured copper oxide combined quartz crystal microbalance, successfully developed a new type of gas sensor .

Selectivity of the study group and team the antichemical College led by Professor Cheng Zhenxing, gas sensing performance of a new type of gas sensor of hydrocyanic acid found that the sensor has excellent sensitivity, fast response and recovery, almost single-minded good repeatability and stability and wide linear detection range characteristics of gas sensing performance is significantly better than the previously reported hydrocyanic acid sensor.

Research has applied for a Chinese invention patents, research papers were published in Environmental Science and Technology, 2011, 45, 6088-6094, Sensors and Actuators B 2011, 155, 692-698, Joual of Colloid and Inte rf ace Science 2011 355, 15-22, attracted much attention, and was invited in the Joual of Colloid and Interface Science writing Feature art ic le (2011, 355, 15-22).

The research is expected to be applied to the gas array sensor, wireless sensor networks, portable detection device at the same time provides a useful reference for the research and development of other gas sensors.

The research work was the subject of the CAS Knowledge Iovation Key Project support.
