Can the size of TiO2 powder be becreased if it was dissolved in 2.5 M NaOH, then Precipetated by 1 M conc. HCL, according to the following equations:
TiO2 + 2NaOH = Na2TiO3 + H2O
Na2TiO3 + 2HCL = 2NaCL + TiO2 +H2O
??
and if it is not possible, what will be the best method to prepare TiO2 nanoparticles with size less than 50 nm ??
Thanks in advance.
