Abstract

Highlights: Pure SnO2 nanoparticles are synthesized by chemical precipitation method. XRD, FESEM with EDAX and Antibacterial activity analyses were carried out. XRD results showed the particles are crystalline in nature with tetragonal structure. FTIR analysis confirmed the formation of sn-O bonds. FE-SEM images showed presence of spherical nanoparticles of size 23 nm. The antibacterial activity of SnO2 nanoparticles is tested against various pathogenic bacteria viz., Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa by zone of inhibition method. Abstract: The tin oxide (SnO2 ) nanopowders were synthesized by a simple chemical method (precipitation). The sample was studied for XRD, FESEM, and EDX analyses. The XRD results of synthesized SnO2 nanoparticles exhibited a tetragonal structure with an average crystallite size of 18.79 nm. The FE-SEM exhibited the microstructure of the prepared nanoparticles. The FESEM images reveal that the shape of the prepared product wasspherical. The impact of SnO2 NPs on food and water poisoning growth was investigated with the help of antibacterial activities. This paper deals with the properties and applications of tin oxide nanostructures. Antibacterial activity was carried out against three bacterial strains: Bacillus subtilis, Escherichia Coli, and Pseudomonas aeruginosa.
