| 摘 要： | The TiO2 microspheres were deposited on the glass substrates under certain conditions via hydro-thermal reaction using 0.15 mol·L?1 TiCl3 saturated NaCl aqueous solution adding urea as an additive. The TiO2 is characterized rutile by results of SEM,TEM and XRD techniques,the TiO2 microspheres are large scale assembled from TiO2 nanorods. The affections on the products by the factors of the con-tents of urea being an additive(the key techniques) ,the reaction temperature,the reaction time and the concentration of TiCl3 were studied. The optimum condition was found,and the mechanism of reac-tions was discussed also.

| Abstract: | The TiO2 microspheres were deposited on the glass substrates under certain conditions via hydrothermal reaction using 0.15 mol·L-1 TiCl3 saturated NaCl aqueous solution adding urea as an additive.The TiO2 is characterized rutile by results of SEM, TEM and XRD techniques, the TiO2 microspheres are large scale assembled from TiO2 nanorods. The affections on the products by the factors of the contents of urea being an additive (the key techniques), the reaction temperature, the reaction time and the concentration of TiCl3 were studied. The optimum condition was found, and the mechanism of reactions was discussed also. |
