Abstract: One of the challenges in metal oxide gas sensors is to achieve high sensitivity and selectivity towards specific gases of interest while minimizing cross-sensitivity to other gases present in the environment. This requires careful design and engineering of the sensor materials and operating parameters. Gas sensing applications of binary metal oxides have been an area of significant interest due to their high sensitivity, low cost, and stability. Binary metal oxides have shown promising results in detecting various reducing and oxidising gases, such as LPG, NH4, CO, NOx, H2S, and VOCs. These metal oxides exhibit semiconducting properties, and their conductance changes when exposed to different gases, enabling their use in gas sensing applications. The future prospects for gas sensing applications of binary metal oxides are promising, with ongoing research focused on enhancing their selectivity, sensitivity, response time, and stability. Integration with advanced technologies such as nanomaterials, nanocomposites, and functionalization with noble metals or other catalytic materials is expected to further improve the performance of binary metal oxide gas sensors. Additionally, the development of miniaturised and portable gas sensors for environmental monitoring, industrial safety, and healthcare applications is a growing area of interest. This review points out the shortcomings of the existing work on binary metal oxides. The main aim of the current review article is to provide brief information on applications and methods of preparation of binary metal oxides.
