There are different methods to introduce metal ions into TiO2 lattices, however some of them are costly. Can someone suggest a simple, economical method?
You can use the sol-gel method including a salt with another metal ion. After, you can study the possible introduction by XRD or HRTEM.
Thanks for your reply. I have done the this in past, but their is problem with this incorporation of metal ion is that there is leaching of metal ion. similar thing is observed in metal ion impregnation using wet impregnation method too.
Yes, I know. Similar results I found too because of metal ion sizes and the preference of TiO2 to form very quickly the anatase phase. Impregnation method is so hard because the mobility of ions and stability of anatase phase. Do you make sputtering method? (I know, this method is very expensive).
Yes .....i have not used sputtering...yes it is expensive...
yes this approach is interesting...but we do not have LASER
Yes by solution precipitation method one can incorporate metal ions into the lattice. You may need to heat the material at specific temperature. However ionic radii of the substituted metal must be close to Ti4+. In addition certain physical methods can be used.
Maybe you can try this method which worked quite well for Kb doping. Of course you do need a spray dryer for this approach
