“Investigation of Single-Crystalline SnO₂ Bipyramidal: Synthesis and Properties”

Abstract

Semiconductor nanostructure metal oxides have attracted a lot of attention due to their unique electrical. optical, and mechanical properties and potential application over their bulk counter parts. Among them. Tin Oxide (SnO2) nanostructures, as an n-type semiconductor with a direct wide band gap (Eg = 3.6 eV at 300K,) and high exciton binding energy (130 meV) have been intensively investigated because of anticipated application in many areas. However, it should be noted that the size and morphology of the material greatly affect their properties and applications.SnO, as an important functional material with various applications. such as gas sensors, solar cells, transparent conducting electrodes and in catalysis, were synthesized using simple electrolysis of metal electrode in water at different voltages with ionic conductivity-108 x 103 Siemens and pH 7.85 as electrolyte. The crystal structure, surface morphology and chemical composition of the as synthesized product were analyzed using XRD, SEM and EDAX techniques respectively. In the present study, we report the synthesis and characterizations of nanostructure SnO, bipyramids.
