Abstract
Tin oxide nanoparticles with crystallite size (1.9-3 nm) were synthesized via hydrothermal route. The role of autoclave temperature (T
A
) on the structural parameters and surface morphology of the as-synthesized SnO
2
nanoparticles (NPs) was followed using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The thermal behavior of the as-synthesized SnO
2
NPs was carried out using thermogravimetric and differential thermal analysis (TGA/DTA) techniques under non-isothermal conditions. The effect of T
A
on the activation energy of crystal growth (E
c
) and the Avrami exponent (n) of SnO
2
NPs were determined by different methods. The reaction mechanism controlling the growth process was discussed in terms of the results obtained using different iso-conversional methods to determine the local E
c
(α) and n(α).
