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.</p>}, number={1C}, journal={Hue University Journal of Science: Natural Science}, author={Đặng , Thị Thanh Nhàn and Hoang, Thi Trang and Ngo, Duy Y and Lê, Quốc Thắng}, year={2021}, month={Sep.}, pages={97-104} }
