| Abstract: | High surface area  -AlF3 has been prepared by a carbon hard template method, Wherein  -Al2O3 is immersed with sucrose aqueous solution and the dried mixture thermally treated under N2 flow at 450 oC to obtain the C@-Al2O3. C@-Al2O3 can be completely transformed to C@-AlF3 with hydrogen fluoride at 400 oC. After the carbon template in C@-AlF3 is removed by high temperature combustion, a high surface area -AlF3 (66 m2 g-1) is obtained. It is found that the fluorination process is crucial for the resulting -AlF3. Although high fluorination temperature is favorable to the formation of -AlF3, it also results in the decline of surface area. |
