Novel Gas Sensor Technology

Researchers from King Abdullah University of Science and Technology (KAUST) find fluorinated metal-organic frameworks (MOFs) make excellent materials for selective sensing and removal of toxic gases.

From astronauts and submariners to miners and rescue workers, people who operate in small enclosed spaces need good air quality to work safely and effectively. Electronic sensors now developed by a team at KAUST can simultaneously detect at least three critical parameters that are important to monitor to ensure human comfort and safety.

These new sensors use MOFs as the sensing layer. MOFs are porous materials comprising a regular array of metal atoms held together by small organic-molecule linkers to form a repeating cage-like structure. KAUST’s Mohamed Eddaoudi, who led the two studies of the sensor’s efficacy, explains that by altering the metal and organic components, MOFs can be tuned for applications ranging from gas separation and storage to catalysis and sensing.

“Many people have attempted to develop simple, efficient, low-cost SO2, CO2 and H2O sensors without success,” say researchers Mohamed Rachid Tchalala, Youssef Belmabkhout and Prashant Bhatt, all from Eddoudi’s lab.

The approach taken by Eddaoudi’s group was to develop a fluorinated MOF, which Belmabkhout and Tchalala tested as sensor materials for these gases. Testing of these state-of-the-art materials was in collaboration with Khaled Nabil Salama and his team.

“electronic sensors now developed by a team at KAUST can simultaneously detect at least three critical parameters that are important to monitor to ensure human comfort and safety”

The first study shows how the sensor can measure the concentration of carbon dioxide and the level of humidity in the air1, while the second study of the same fluorinated MOFs shows it can detect the harmful and corrosive gas sulphur dioxide, or even selectively remove it from powerplant flue gas2.

“Traces of SO2 are invariably present in the flue gas produced by factories and powerplants, and SO2 can poison materials developed to trap CO2 for carbon capture and storage,” say Belmabkhout and Bhatt. “AlFFIVE-1-Ni can soak up SO2 with an affinity 66 times higher than for CO2, while showing good stability to SO2 exposure.”

The MOFs could also be used with two simple, low-cost high-sensitivity sensor platforms. Quartz crystal microbalance (QCM) sensors that are coated with a thin film of either MOF detected the change in mass with the absorption of SO2, or water and CO2. Similarly, MOF-coated interdigitated electrode sensors detected a change in electronic properties with the absorption of water and CO2.

Both sensor platforms, the team showed, could monitor moisture and CO2 levels under real atmospheric conditions. “The signal is calibrated against CO2 concentration, humidity level and mixtures of both,” Tchalala explains. A QCM-based sensor could also detect SO2 in the air at levels of just 25 parts per million.
