Project Description

This project is intended to investigate and deliver high-temperature oxygen sensors based on pure and doped gallium oxide (Ga2O3) nanostructures operating at 800 °C and above in a corrosive atmosphere. The impetus is designing the Ga2O3-based nanostructured materials for application as oxygen sensors operating at extremely high temperatures in fossil fuel energy systems with a demonstrated reliability, stability and without any interference from other pollutants/emissions.

Project Benefits

This project will design gallium oxide (Ga2O3)-based nanostructured materials capable of operating under extreme conditions. The expected impact of this technology is lower operating costs through more accurate measurements of the conditions inside a gasifier or boiler to better control their operation. Improved O2 sensors will also contribute to the development of cleaner and more efficient coal-fired power generating plants.
