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

Shikha Yadav, Shreya, Peeyush Phogat, Ranjana Jha, Sukhvir Singh

Abstract: 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 charac-teristic contributes to enhanced sensitivity and adsorption capabilities. In this study, the chemical co - precipitation method was uti-lized to synthesize SnO2 nanoparticles. Among the suggested techniques, the chemical co - precipitation approach has various bene-fits such as simplicity of use, minimal laboratory equipment requirement, low impurity levels, shorter processing time, and reproduc-ibility. Hence, technique was adopted to synthesis of SnO2 nanoparticles (NPs). The tetragonal crystal structure of the highly crystal-line 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).
