Abstract:
An approach to spectral analysis of the energy-band-structure parameters (bandgap width and Urbach energy) of potassium polytitanate (PPT) nanoparticles modified by transition metals is proposed, which can provide a basis for the synthesis of new photocatalytic materials. It is established that the modified PPT samples are characterized by reduced values of the bandgap width and higher values of the Urbach energy as compared to the initial material. Possible mechanisms of this phenomenon are discussed.
