Dear Milad, thank you for posting this interesting technical question. Fortunately zirconyl chloride (ZrOCl2 x 8H2O) is highly soluble in water. Thus you can adapt the synthetic procedure described in the literature reference cited below in which zirconium nitrate was used originally:

Comparative study of naphtha cracking over SAPO-34 and HZSM-5: Effects of cerium and zirconium on the catalytic performance

Article Comparative Study of Naphtha Cracking over SAPO-34 and HZSM-...

Unfortunately this article has not been posted as public full text on RG. Here are the most important points in short: The catalyst precursor SAPO-34 was purchased from a commercial source. I assume that you have it already available in your lab. The impregnation is done using a rotary evaporator in aqueous solution / suspension. The desired stoichiometric amount of ZrOCl2 x 8H2O is dissolved in 25 mL of deionized water, and the SAPO-34 catalyst is added to this solution. The zirconium content in the impregnated catalysts can be e.g. ca. 2 wt%. The resulting suspension is then evaporated to dryness under vacuum at 75 °C using the rotary evaporator and the resulting solid is dried in an oven at 120 °C for 2 hours. Finally, the impregnated catalyst is calcined at 750 °C in air for 2 hours and and then allowed to cool to room temperature. The impregnated catalyst can be used as pellets or as powder.

I hope this helps. Good luck with your work and best wishes!

Dear Milad,

I have attached a paper on ZnO impregnated mesoporous ZSM5 which is what I am currently working on. You can use a similar procedure for your ZrO2 impregnation on SAPO-34.

Regards.

Dear Prof. Frank T. Edelmann thank you so much for replying, It was really helpful.

I got very good information from your answer.

best wishes

Dear Livingstone Udofia

I'm so thankful to you, but I have ZrOCl2.8H2O, and you used Zn(NO3)2

The first is chloride and the second is nitrate.

I think the procedures are different.

my problem is impregnation with ZrOCl2.8H2O.

kind regards.
