Facile synthesis of ZnIn₂S₄/Cu₂O hierarchical heterostructures for enhanced selectivity and sensitivity of NH₃ gas at room temperature

The development of an effective and reliable sensor with the capability to detect ammonia (NH₃) gas at room temperature exerts a significant influence on the sensor industry. The gas sensing performance is notably improved by the formation of a heterostructure between metal oxide with metal sulfides. In this study, pure ZnIn<sub>2<...

Spark Ablated Metal Oxide Nanoparticles for Gas Sensing

Metal oxide nanoparticle gas sensors showpromise due to their high sensitivity towards a wide range of gases, low costs, and low complexity. Particle sizes at nanometers offer a high surface-to-volume ratio which provides more areas on the surface where reactions can occur. This work presents the application of spark ablated nanoparticles on...
