Characterization and photocatalytic activity of
Ti/TinOm ∙ ZrxOy coatings for azo-dye degradation

Title variants
Languages of publication
Anodic oxidation of VT1-0 titanium and E-125
zirconium alloy in aqueous electrolyte solutions based
on H2SO4 and K4P2O7 was used to obtain oxide coatings
composed of Zr/ZrO2, Ti/TiO2, and mixed oxide systems
Ti/TinOm ∙ ZrxOy. It was shown that, depending on the
electrolyte рН, the films contained from 0.17 to 2.1% wt.
of zirconium. The catalytic activity of the synthesized
coatings in the oxidation reaction of the methyl orange
azo dye under UV irradiation was established. The process
rate constants and synergy factors for the mixed systems
were calculated.
