BPN954: Quantum Dots Based High-performance Gas Sensors

Sikai Zhao
2020

In recent years, the demands for high-performance gas sensors are rapidly increasing in many fields including environmental monitoring, public health and security, medical diagnostics, and industrial process monitoring. Among various types of gas sensors, the resistive metal-oxide-semiconductors (MOS) are very attractive and widely applied due to their high sensitivity, low cost, facile operation, and high compatibility with microfabrication processes. The working principle of such gas sensors is based on the reversible changes in the sensor’s resistance caused by the gas adsorption and...

Among the large family of metal-organic frameworks (MOFs), Zr-based MOFs, which exhibit rich structure types, outstanding stability, and intriguing properties and functions, are foreseen as one of the most promising MOF materials for practical applications. This project aims to leverage the excellent adsorption capacity of Zr-MOFs to acidic gases such as NO2, SO2 and CO2 to develop sensing materials that respond to these target gases by changing color. MOF-808 is chosen due to its large pore size of 18.4 Å and excellent stability in acidic environments. Basically, amines including...
