The existing approaches of the synthesis of silica-alumina mixed oxides were reviewed, including sol-gel method, precipitation method, hydrothermal synthesis method, mixing method and impregnation method. Due to the high specific surface area, large pore volume and narrow pore distribution, sol-gel method was widely used. The current situation of the mixed oxides as catalyst support was introduced. Besides, the existing problems and the future directions have also been discussed.
