Competition between oxygen and water molecules on SiO2/P-doped Si surface: The electrical dipole evolution on water/oxygen-adsorbed oxide surface

Yu-Hsiang Huang et al.

Summary: The performance of gas sensors in humid environments is influenced by the interaction between water and oxygen molecules. This study investigates the competitive adsorption behaviors of oxygen and water vapor using the charge trapping characteristic and observing the evolution of second harmonic generation. By analyzing the trapping time constant, a dynamic model is proposed to explain how water molecules weaken oxygen adsorption and form a water adsorption layer. The results show that the electric field created by charge trapping can align water molecules and enhance the second harmonic generation intensity. This research provides insights into solving water-sensor interaction problems in gas sensors by analyzing the net surface dipole change caused by adsorption-desorption on the SiO2 surface.

Selectivity in trace gas sensing: recent developments, challenges, and future perspectives

Puspendu Barik et al.

Summary: Selectivity is a crucial factor in trace gas sensing, but the current research on selectivity is limited. Existing reviews focus on specific types of sensors or technological developments, lacking a comprehensive assessment of selectivity. Solid state sensors, which are flexible, portable, and cost-effective, have been the main focus of research, but their selectivity is low in harsh environments. Therefore, this paper evaluates the limitations and possible solutions to selectivity issues in different gas sensors, and discusses future prospects.

Nitrous Oxide Is No Laughing Matter: A Historical Review of Nitrous Oxide Gas-Sensing Capabilities Highlighting the Need for Further Exploration

JoAnna Milam-Guerrero et al.

Summary: Nitrous oxide, also known as laughing gas, is a highly detrimental greenhouse gas that is often overlooked. This review focuses on low-cost gas-sensing technologies, such as metal oxide semiconductors, chemiresistive sensors, and electrochemical sensors, for monitoring and detecting nitrous oxide emissions. The use of metal-organic frameworks for compositional modifications is also discussed to improve sensing performance.

Perovskite-structured LaCoO3 modified ZnO gas sensor and investigation on its gas sensing mechanism by first principle

Wenbo Qin et al.

Summary: LaCoO3 nanoparticles were synthesized by sol-gel method and modified on the surface of ZnO to prepare LCO/ZnO nanometer flake materials with improved gas-sensitive response. The LCO/ZnO sensor showed significantly enhanced response to ethanol gas, shorter response time and recovery time at an optimal operating temperature of 320 degrees C. Analysis of the sensitization mechanism revealed that the improved sensing performance was attributed to the increase of surface adsorbed oxygen content and the strong catalytic oxidation activity of LCO.
