Development and production of heterostructured thin films with unique properties for highly effective detection of hazardous gases

Project goal: The goal of this project is to develop highly sensitive sensors with a composite structure based on metal oxide semiconductors (MOS). By improving the optical-electric properties of thin heterostructure films, the sensitivity and response time to various toxic gases will be increased. Sensors will be obtained that are applicable in industries, mines, mining and oil and gas industries, as well as in devices for monitoring indoor and outdoor air quality.
Project description: In recent decades, there has been increasing public attention to the problem of air and environmental pollution. An increase in the concentration of toxic gases, such as NOx, SOx, COx, etc., calls into question the need for effective detection of these substances. Metal oxide semiconductor (MOS) sensors are widely used as an intensively developing type of sensor for detecting gases and vapors. Their attractiveness for industrial applications is due to their low cost, ability to operate in various temperature conditions and a wide range of gas detection. This research project will explore and develop new high-performance sensors based on MOS heterostructures, with a focus on improving the core-shell structure. A variety of techniques will be used, complementary to each other, to create sensors capable of detecting low-abundance gases in the atmospheric environment.

Realisation period: 2024-2026
Expected results: - at least 2 (two) articles and (or) reviews in peer-reviewed scientific publications in the scientific direction of the project, indexed in the Science Citation Index Expanded of the Web of Science database and (or) having a CiteScore percentile in the Scopus database of at least 50 (fifty);
- or at least 1 (one) article or review in a peer-reviewed scientific publication in the scientific direction of the project, indexed in the Science Citation Index Expanded of the Web of Science database and (or) having a CiteScore percentile in the Scopus database of at least 50 (fifty), and not less than 1 (one) patent on the subject of the project included in the Derwent Innovations Index database (Web of Science, Clarivate Analytics);
- or at least 1 (one) article or review in a peer-reviewed scientific publication, indexed in the Science Citation Index Expanded and included in the 1 (first) quartile by impact factor in the Web of Science database;
- at least 1 (one) patent for an invention (including a positive decision on it).
Methodology: The gas sensing properties of MOS sensors will be improved by modifying the surface of the sensing material using core-shell structures. In this project, thin nanostructures will be obtained using cost-effective methods such as electrospinning, sequential ion layer adsorption (SILAR), and hydrothermal. A combined electrospinning/SILAR method and hydrothermal/chemical deposition for gas sensors will be used for the first time to achieve thin heterostructures. In addition, a gas sensing sensor using the Arduino platform will be developed and tested in the project.
