Abstract

In this work, rod-flower-like SnO2 hierarchical micro-nanostructures are successfully synthesized via pyrolysis of SnO2/chitosan in a nitrogen atmosphere. The effects of the heating temperature, time and rate of the thermolysis on the morphologies of the as-prepared products were evaluated. The optimized parameters to synthesis flower-like ensembles composed of nanorods found are as follows: temperature 500 °C, time six hours, and heating rate 10 °C/min. The structural properties of the material are systematically investigated by using X-ray diffraction (XRD), scanning electron microscopy (SEM), and thermogravimetric analysis (TGA). The mechanism of the material formation is proposed.
