Preparation of Tin Oxide Nanoparticles via Co-Precipitation Method for its Future Applications

Tin oxide have gained significant attention due to their wide application in optoelectronics, electrodes for lithium -ion batteries, solar cells and gas sensing applications. Owing to its mechanical stability, as well as a high surface -to -volume ratio in comparison to bulk tin oxide, tin oxide (SnO2) serves as an n -type wide band -gap semiconductor in gas sensing devices. This unique characteristic contributes to enhanced sensitivity and adsorption capabilities. In this study, the chemical co -precipitation method was utilized to synthesize SnO2 nanoparticles. Among the suggested techniques, the chemical co -precipitation approach has various benefits such as simplicity of use, minimal laboratory equipment requirement, low impurity levels, shorter processing time, and reproducibility. Hence, technique was adopted to synthesis of SnO2 nanoparticles (NPs). The tetragonal crystal structure of the highly crystalline SnO2 material was verified by X -ray diffraction (XRD) analysis, revealing a crystallite size of approximately 13 nm using the size -strain plot. Additionally, the absorbance plot and band gap value of the synthesized SnO2 nanoparticles were determined using UV -Vis spectrophotometer. The morphological features of the as -prepared sample were examined using field emission scanning microscopy (FESEM).
