Synthesis of tio2 and sio2 nanoparticles using sol gel method, what should be the ideal PH?
Most of the articles do not write how much PH should be.
i want to do stainless steel coating by tio2 and sio2 nanoparticles for air treatment
Reham Dabboura It is important to use correct terminology in any scientific discourse. People may get the wrong impression of you if you're using terms such as tio2 (rather than TiO2) and PH (rather than pH). Search the literature (including Research Gate) for recipes for your application.
Dear Reham Dabboura ,
I suggest searching the literature in order to know more about the influence of the pH on the sol-gel process of these nanoparticles. Nevertheless, regarding SiO2 nanoparticles, usually pH below 7 tend to form poorly crosslinked gels while pH above 7 tend to form nanoparticles. A lot of articles show the dependance of the size of the nanoparticles and the pH and recipes employed.
Reham Dabboura
It depends on the size of the nanoparticles you want. An acid pH provides smaller sizes than a basic pH. Something similar with coatings, but a greater width carries a greater risk of cracking. I think an acid pH (2.00-4.00) is better in your case in coatings.
