How to determine the conduction band edge of a heterostructure catalyst like TiO2 given the overal band gap and the valence band edge potentials?

I want to calculate the conduction band edge of my TiO2 sample having three phases making a heterostructure. I have got the band gap (nearly 3 eV) from UV-Vis spectroscopic analysis. I also have...
