摘要
We have studied the phase transitions, morphology, and photocatalytic activity of composites based on titanium(IV) and cobalt(II) oxides at Co doping levels from 0.5 to 60 wt % and heat-treatment temperatures from 80 to 1150A degrees C. The highest photocatalytic activity under illumination in the spectral range lambda a parts per thousand yen 670 nm is offered by mesoporous X-ray amorphous and multiphase (X-ray amorphous phase, anatase, rutile, and CoTiO3) nanomaterials containing 5-20 wt % Co, whereas two-phase materials (rutile + CoTiO3) have the lowest photocatalytic activity.
