Influence of heat treatment on the properties of tin oxide nanoparticles: A potential material for environmental remediation applications

Metal oxides have gained a growing interest in the field of material science owing to their size and shape dependent physiochemical properties. Tin oxide (SnO2) is considered as multifaceted with its widespread applications such oxidation catalysis, energy harvesting, bio-imaging, gas sensing, storage devices many more. This study reports synthesis SnO2 nanoparticles derived via sol-gel route. To observe effect thermal treatment on grown material, samples were subjected calcination at different temperature ranging from 350 °C 550 °Cfor about 4 hrs. The structural, compositional, morphological optical properties studied by XRD, EDAX, FESEM, UV-Vis spectroscopic analysis respectively. XRD pattern consists only peaks preferred orientation along (110) plane. crystallite increases higher found range 3-15 nm. All corresponding matches standard data indicating growth good quality single phase material. Compositional reveals that manifested required stoichiometric ratio SnO. Scanning electron micrographs show uniform particle 10-20 band gap calculated studies was 3.1eV 3.0 eV for 450 °Cand °Crespectively. lies visible region solar spectrum which could be beneficial enhanced photocatalytic performance nanoparticles.
