Roman Kubrin

Are you sure your perovskite material enters mesopores of titania? and, if yes, that it crystallizes inside? How did you measure grain size? Any TEM available?

Saeede Tafazoli

Dear Kubrin,

I am not sure, and that is exactly my question for further steps. Can we use TEM for to determine TiO2 porosity? Because BET here is just available for powder.
