FOLETTO, E. L. et al. Influence of reaction time on the properties of Zn₂SnO₄ nanoparticles obtained by hydrothermal method. Lat. Am. appl. res. [online]. 2013, vol.43, n.1, pp. 23-27. ISSN 1851-8796.

This work investigates the influence of reaction time (ranging from 12 to 96 h) on the characteristics of zinc stannate (Zn₂SnO₄) nanoparticles obtained by the hydrothermal method at 200°C. The nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), surface area measurements (BET) and infrared spectroscopy (IR). The results showed that the reaction time influenced the properties of Zn₂SnO₄ nanoparticles. The product presented a pure crystalline phase with mean particle size about 20 nm and BET surface area ranging from 34 to 43 m².g^-1.
