To find out a particular solid is photocatalytic or not, the above energy band gap is useful.
Probably difference from the lower to higher absorption levels of wavelength.
We can find the energy band gap using the tauc plot model
as in the attached file.
we may use direct or indirect band gap depending upon our material's property.
@Ahmad sousaraei
it is 1239/Wavelength= in ev.
I agree with Aleksey, absorption edge technique is reliable method of calculating band gap.
Here you can find good explanation and band gap calculator,
