Year: 2024
Type: article
Abstract: This work examines the combustion synthesis of cadmium (Cd) doped nanocrystalline indium oxide (In2O3) and its gas-sensing potential. This flexible n-type semiconductor, indium oxide, has great potential for gas-sensing applications due to its high sensitivity and quick reaction to diverse gases. Strategic doping improves its performance. Cadmium doping was used to enhance gas-sensing capabilities in In2O3 by altering its structural, optical, and electrical characteristics. Combustion synthesis produces nanocrystalline materials with excellent purity and controllable shape quickly, cheaply, and scalable. Crystalline structure, shape, elemental content, and optical characteristics of produced Cd-doped In2O3 nanomaterials were confirmed using XRD, SEM, EDX. The material's sensitivity, selectivity, and response-recovery to hydrogen, ammonia, and volatile organic molecules were tested in gas sensing tests. The study found that Cd doping improved gas-sensing capability in In2O3, including increased sensitivity, quicker reaction times, and reduced response times.
