Boosting NO sensing performance of CuO by Li-Doping: Synergistic regulation of oxygen vacancies and microstructure

Puntos clave

• NO sensing performance increases with lithium doping—particularly due to enhanced oxygen vacancies and optimized microstructure.
• The introduction of lithium modifies both the electronic properties and the surface characteristics of CuO, leading to superior sensor responses.
• Analysis employed various characterization techniques to evaluate the impact of lithium on the microstructure and NO sensing capabilities of CuO materials.
• These findings may enable the development of high-performance NO sensors for environmental monitoring and gas detection applications.
