Документ Synthesis and photocatalytic activity of Ti/TinOm ∙ ZrxOy coatings for azo-dye degradation(Національний технічний університет "Харківський політехнічний інститут", 2015) Bykanova, V. V.; Sakhnenko, N. D.; Ved, M. V.; Nikiforow, K. V.; Maiba, M. V.Anodic oxidation of ВТ1-0 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· Zr xOy with synergetic effect. It was established mixed oxide materials contain from 0.17 up 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 shown. The process rate constants and synergy factors for the mixed systems were calculated.
