[0039] The preparation method of POMOF catalyst comprises the following steps:
[0040] Step (1), 0.9624g ZrOCl 2 ·8H 2 O and 0.6996g of terephthalic acid were dissolved in 50mL of dimethylformamide solution; then transferred to a 100mL capacity reactor, heated at 120°C for 12 hours and then cooled;
[0041] Step (2), centrifuge the product obtained in step (1) with an 8000rpm centrifuge, remove the liquid, then add dimethylformamide to wash and continue centrifuging, remove the liquid; then add water to wash and then centrifuge again, remove liquid; finally add ethanol to wash and continue to centrifuge, remove the liquid;
[0042] Step (3), cycle step (2) once, after removing the liquid for the last time, place the centrifuge tube containing the solid in an oven at 100°C for 12 hours to obtain UiO-66;
[0043] Step (4), get 1g UiO-66 and 0.1-1g H 3 [P(W 3 o 10 ) 4](PW) was dispersed in 100mL of water, put into a reflux device containing a 250mL round bottom flask, ref...
Embodiment 1
[0050] Put 0.67mmol of furfural, 0.1g of POMOF-PW-0.5, and 20ml of isopropanol into a 35mL autoclave. After sealing the autoclave, stir and react at 160°C for 23h. After the autoclave is cooled, it is ready to be tested.
[0051] The preparation method of the POMOF catalyst is as follows: dissolve 0.9624g ZrOCl2 8H2O and 0.6996g terephthalic acid in 50mL dimethylformamide (DMF); then move it into a 100mL capacity reactor, heat it in water at 120°C for 12h and then cool it down . Then centrifuge with 8000rpm centrifuge to remove the liquid, then add dimethylformamide to wash and continue to centrifuge to remove the liquid; then add water to wash and then centrifuge again to remove the liquid; finally add ethanol to wash and continue to centrifuge to remove the liquid ; The aforementioned steps of washing and centrifugation were cycled once, and after the liquid was removed for the last time, the centrifuge tube containing the solid was dried in an oven at 100°C for 12 hours, an...
