Embodiment 1
[0018] Preparation of aluminum phosphate aluminum oxide APO: Dissolve 58.8g aluminum nitrate and 22.3g diammonium hydrogen phosphate in 500ml deionized water at room temperature, stir for 1 hour, add 10ml concentrated nitric acid for acidification, continue to drop concentrated ammonia water to adjust the pH value to 8 , filter the formed precipitate, wash with deionized water for 3 times, dry at 120°C overnight, and then dry and roast at 500°C to obtain phosphorus aluminum oxide APO-1, determined by ICP-AES, the content of Al in APO-1 Take Al 2 o 3 Calculated as 40%, the content of P is P 2 o 5 Count as 60%.
Embodiment 2
[0020] The preparation steps of aluminophosphate APO are the same as in [Example 1], except that the amounts of aluminum nitrate and diammonium hydrogen phosphate used are respectively 14.7g and 33.5g to obtain aluminophosphate APO-2, which is determined by ICP-AES. The content of Al in -2 is expressed as Al 2 o 3 Calculated as 10%, the content of P is P 2 o 5 Count as 90%.
Embodiment 3
[0022] The preparation steps of aluminophosphate APO are the same as in [Example 1], except that the amounts of aluminum nitrate and diammonium hydrogen phosphate used are respectively 36.8g and 27.9g to obtain aluminophosphate APO-3, which is determined by ICP-AES. The content of Al in -3 is expressed as Al 2 o 3 Calculated as 25%, the content of P is P 2 o 5 Count as 75%.
