Embodiment 1
[0025] Add 1.0 g of 1-hydroxyethylidene-1,1-diphosphonic acid (abbreviated as HEDP) and 0.3 g of cetyl alcohol polyoxyethylene ether to 25 ml of water, stir at 35 °C for 1 hour, slowly drop Add 1.0 g of zirconium isopropoxide (purity: 99.9%, Bailingwei Technology Co., Ltd.), continue to stir at a slow speed for 1 hour, put it into a reaction kettle and crystallize at 80 ° C for 24 hours. The solid product was filtered and extracted with ethanol in a Soxhlet apparatus for 24 hours. Then it was added to 10 ml of a mixed solution of anhydrous pyridine (AR, Tianjin Concord Technology Co., Ltd.) and chlorosulfonic acid (AR, product of Gracia (Chengdu) Chemical Technology Co., Ltd.) in a volume ratio of 1:1, slowly After stirring for 5 hours, the mixture was filtered, washed with water and dried.
[0026] The material has a BET specific surface area of 610m 2 / g, the pore volume is 0.55cm 3 / g, the macropore pore size distribution is 300-500 nm, the mesopore pore size is 1.9 nm...
Embodiment 2
[0028] Using the preparation process of Example 1, 1.5 g of zirconium isopropoxide was added, and the mixture was crystallized at 60° C. for 48 hours.
