Золь-гель синтез TiO2/ZrO2 плівок для фотокаталітичного відновлення Cr(VI) у водному середовищі

Crack-free abrasion-resistant ZrO2/TiO2 transparent films with thickness up to 600 nm on the glass substrates were prepared by the low-temperature sol-gel process from the Zr and Ti alkoxides by using acetylacetone as a chelating agent. The complexing agent controlled the rate of hydrol...

Zusammenfassung:Crack-free abrasion-resistant ZrO2/TiO2 transparent films with thickness up to 600 nm on the glass substrates were prepared by the low-temperature sol-gel process from the Zr and Ti alkoxides by using acetylacetone as a chelating agent. The complexing agent controlled the rate of hydrolysis of the precursor alkoxides, resulting in the formation of homogeneous transparent films stable in strong base and acid conditions. The films with ZrO2/TiO2 ratio 30 : 70 are high active in the photoreduction of toxic Cr(VI) ions to non-toxic Cr(III) ions .
