For c-TiO2 layer onto FTO, I need to make 30 mM titanium diisopropoxide bis(acetylacetonate) (TDBA) solution for spray-pyrolysis.
As far as I know, TDBA is usually sold as a solution in IPA (75wt%).
How could I make 30 mM titanium diisopropoxide bis(acetylacetonate) (TDBA) solution using TDBA in IPA (75wt%) solution?
Is your question about how you should do the dilution from 75%wt to 30mM?
if it is, you should first calculate what is the concentration in mol/L of your 75% stock solution (be careful because the percentage is a wt% so you have to get the density of IPA to get the concentration in g/L that can help https://www.researchgate.net/post/What-is-a-25-wt-solution-of-tetramethylammonium-hydroxide-in-methanol-mean )
then calculate what is the dilution factor you should apply.
for that you need the molar mass of your precursor in g/mol and the density of IPA in g/ml. (I'm not sure if that's the answer you were looking for but I'm sure it could help someone).
