Dear all,
I want to prepare metal oxide catalyst, which is CaO-ZnO/Al2O3.
So, which the best method for that; is it co-precipitation method or incipient wetness method? or you can suggest another method.
Thank you so much in advance.
i suggestion sol gel which you can produce the fine particle and you control the experimental condition. you acn read more about the sol gel method i think you will get that you need to start your experiment then get the target oxide
Dear Muneer,
Thank you so much for your answer.
Do you have an article which describe sol gel method in easy method, please?
I suggest sol gel chemistry as the previous response . It is the best way for a perfect stochiometric control of final product. You can obtain a catalyst with an high specific surface area and absence of co-precipatate. I suggest this old paper Bioactive Ceramics in the CaO-AI203-P2O5-ZnO System Prepared by the Sol-Gel Technology. You can prepare your material in the same way without P2O5
Efficient catalysts can be prepared by impregnation of alumina with Ca and Znsalts and further calcination, if low percentages of calcium and zinc are used. See for example
Particuology Volume 8, Issue 3, June 2010, Pages 225–230
Hi
I think firstly, you need to prepare a good surface area, large pore volume and highly acidic alumina support. Please find the attached paper that discuss the preparation of different phases of alumina
Best regards
Please check out this recent publication at Nature journal about the preparation of highly active alumina catalyst from foil waste
