SnO2 semiconductor nanoparticles were synthesized by an ultrasonic irradiation of aqueous solution SnCl4 and azodicarbonamide under ambient air. These are ∼3−5 nm in size, as calculated using the Debye−Scherrer formula, observed TEM. The also characterized powder X-ray diffraction (XRD), reflection spectroscopy FT-IR spectroscopy, transmission electron microscopy (TEM), DSC, TGA. band gap was from spectroscopy. Electrochemical tests performed electrode's materials nonaqueous Li salt solutions. results showed promising reversibility, cycle life high capacity for lithium insertion into nanoparticles.
