Sol-gel auto-combustion synthesis of SnO2 Nanopowders: Application in Electrochemical Studies

SnO2 with nanosized structures are facilely synthesized by sol-gel auto-combustion method, and their electrochemical properties are investigated. Different techniques contain X-ray diffraction, scanning electron microscopy and energy dispersive X-Ray spectroscopy are applied for study of the nanostructures. Using the techniques crystallization procedure, morphology and particle size of the powders are characterized. For electrochemical studies, a carbon paste electrode is modified with SnO2 nanostructures. Characterization of the nanostructured electrode is performed by voltammetric techniques. Using the techniques electrocatalytic activity of the SnO2 in the presence of a probe solution is studied. The voltammetric data are confirmed that the SnO2 nanostructures are a potential candidate for electrocatalytic analysis in complex samples
