Developing zinc oxide-doped cadmium sulfide nanocomposites chemically for oxygen gas sensing properties via annealing effects

Abstract

Here, we describe the synthesis and properties of zinc oxide (ZnO)-doped cadmium sulfide (CdS) nanocomposites tailored for gas sensing applications. The nanocomposites were prepared using a chemical synthesis method and underwent optimization through annealing processes. The optimized annealing conditions are determined to enhance the gas sensing properties. The gas detection properties of the zinc oxide doped cadmium sulfide nanocomposites are systematically evaluated under various gas atmospheres, including common industrial pollutants. The nanocomposites exhibit promising gas sensing capabilities, demonstrating sensitivity and selectivity towards specific gases. The results indicate that the annealing process significantly influences the gas sensing performance, leading to improved response and recovery times, as well as enhanced selectivity and stability.This research highlights the importance of controlled annealing in tailoring the gas detection properties of nanocomposites. Therefore, the synthesized nanocomposite can be used for a suitable materials for oxygen sensing.
