| Abstract: | As a new catalytic material,TiO2-Al2O3 composite oxide aroused wide concern.The latest progresses of preparing techniques were summarized,such as sol-gel,preprecipitated,gas phase adsorption method,hydrothermal,especially the effect of different sol-gel preparation conditions on the nature of complex oxide of TiO2-Al2O3.It indicated that Al2O3 can improve surface area and thermal stability of TiO2.Some problems and countermeasures were mentioned. |
| Keywords: | TiO2-Al2O3 preparation sol-gel method |
