Abstract

SnO₂ nanomaterial was synthesized using the unseeded, non-catalytic, horizontal vapor phase growth technique. The samples were synthesized at a temperature of 1200^oC and growth time of 6 hours. The resulting nanostructures, as confirmed by JEOL JSM-5310 SEM, ranges from wires to belts to cantilever like structures. The as-grown nanomaterials were then collected and subjected to differential thermal analysis (DTA) and differential scanning calorimetry (DSC) using Perkin Elmer DTA7 differential thermal analyzer. The different thermal kinetic parameters namely, the activation energy, predetermined from DSC measurements using a multilinear regression procedure based on the Borchardt-Daniels model. A growth mechanism is suggested based on the results of the kinetics calculations and on existing models of nanostructure growth.
