Nanosensors for simultaneous electrical and optical monitoring of climate change gases

Project description

Smart and small gas sensors to fight climate change

Climate change increases the risk of extreme and disastrous weather events. There is an urgent need for solutions that improve adaptation and mitigation of climate change. Greenhouse gases, particularly carbon dioxide, nitrous oxide, and methane, are among major contributors to global warming. The emissions monitoring equipment are usually costly, bulky, and complex. The EU-funded NEOGAS project will develop novel gas sensors suitable for Internet of things (IoT) and made from metal-organic framework materials. The developed devices will be tested for greenhouse gas detection and will be benchmarked against environmental reference stations. Capable of delivering multiple readouts, this technology will be more efficient.

Objective

The emission of greenhouse gases (GHGs), especially of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), is the major source of global warming and climate change. To monitor their emissions, one can find in the market highly sensitive and selective, complex, bulky and expensive instruments, used as reference measuring systems, which can only be installed in few specific locations. For an accurate spatial control of these emissions, however, large number of sensing systems need to be installed and connected, benefitting from Internet of Things (IoT) and providing the required ubiquity. Usually these devices do not need to meet the sensitivity level of the reference instruments.

The present project addresses the development, fabrication and testing of gas sensors, suitable for IoT, made from advanced metal organic frameworks (MOFs) materials. These gas sensors will be multivariable devices, providing the simultaneous readout of the change of electrical and optical properties when exposed to gaseous species, in opposition to standard gas sensing devices, that deliver one single readout. This innovative approach is expected to present advantages over the standard devices, especially in terms of miniaturization, compactness and selectivity, as they are integrated nanoelectronic noses. The developed devices will be tested towards GHGs and will be benchmarked against environmental reference stations.
