Nanocomposite Sensors Detect Toxic Gases

Iranian and South Korean researchers synthesized nanocomposites to be used in the production of sensors to detect toxic gases


Iranian researchers from Shiraz University in association with their colleagues from South Korea synthesized nanocomposites to be used in the production of sensors to detect toxic gases and gas pollutants, including carbon monoxide.

Sensors made of the mentioned nanocomposite have higher sensitivity and efficiency in comparison with the normal ones while they require less production cost. These sensors can be used in industrial centers, automobiles, hospitals and houses.

Carbon monoxide is a colorless, odorless and tasteless gas that is fatal at high concentrations, and it is known as silent murderer. The aim of the research was to design a gas sensor by using nanocomposites to quickly detect carbon monoxide at low temperature. To this end, samples of a nanocomposite were produced, and their performance was determined in the detection and measurement of carbon monoxide in the environment.

According to the researchers, the ability to perform at low temperature and short time of detection are two important parameters in designing a sensor to detect carbon monoxide and other gas pollutants. The sensor produced in the research has a very simple production method as well as high sensitivity to carbon monoxide at low temperature in a very short time. Therefore, it is more sensitive than other diagnosis sensors and it has higher efficiency. In addition, it has a cost-effective production method with no specific difficulty.

Results of the research have been published in Journal of Hazardous Materials, vol. 35, 2016, pp. 130-138.
