We have studied the phase transitions, morphology, and photocatalytic activity of titanium(IV) oxide-cerium(IV) oxide materials at Ce doping levels from 1 to 20 wt % and heat-treatment temperatures from 80 to 1150A degrees C. The highest photocatalytic activity under illumination in the spectral range lambda aeyen 670 nm is offered by mesoporous X-ray amorphous and multiphase (X-ray amorphous phase + anatase + rutile + CeO2) nanomaterials, whereas the two-phase materials (rutile + CeO2) have the lowest photocatalytic activity.
