The present invention relates to the methods that one kind efficiently prepares porous high-specific surface area amorphous TiPO, comprising: instills the ethanol solution containing titanium source in 70~100 DEG C of phosphate aqueous solution, then is centrifuged, is washed, obtains colloidï¼›After drying by gained colloid, it is heat-treated 2~5 hours at 400~600 DEG C, obtains amorphous TiPO material.The present invention uses hot water drop-method for the first time, uses phosphoric acid as additive, and amorphous state is still maintained after (400 DEG C, 500 DEG C) of subsequent high temperature heat treatment. |
