摘要：In comparison with pure titanium dioxide, the catalyst absorbs light in the wave band up to 400 nm. A strong absorption band is exhibited in the X-ray photoelectron spectrum (XPS) in the range 280-290 eV, relative to the Ols band at 530 eV. The carbon content is 0.4-4 wt%, based on the total weight of photocatalyst. The photocatalyst has a strong absorption band in the x-ray photoelectron spectrum at 284.5 eV, relative to the Ols band at 530 eV. The photocatalyst has in addition, weaker absorption bands at 289.4 and 294.8 eV, relative to the Ols band at 530 eV. The photocatalyst also exhibits carbonate bands at 1738, 1096 and 798 nm. The photocatalyst has a strong absorption band in the x-ray photoelectron spectrum at 285.6 eV relative to the Ols band at 530 eV. It has superhydrophilic properties. An aluminum platelet coated with the photocatalyst forms a contact angle with water of about 8[deg]. The titanium dioxide in the photocatalyst, exists as the anatase crystal modification.
