TiO2 and CdS based heterostructures (HS) with biscyanine – cyanine pigment comprising two conjugated chromophores as a sensitizer have been synthesized. Absorption spectra of HS have been analyzed and their photocatalytic activity (PA) in the reaction of methylene blue reduction was determined. Energy transformation and electron transferring processes induced by various spectral zones irradiation have also been described. It has been found that photocatalytic activity depends on the pigment concentration in HS. Interrelation between changes in PA and some important spectral parameters has also been determined.
