Title: Formation of freestanding ZrO{sub 2} nanotubes for Cr(VI) removal

Abstract

Freestanding ZrO{sub 2} nanotubes (ZNTs) were produced using a simple anodization method in fluorinated ethylene glycol electrolyte containing 1 ml 1 M K{sub 2}CO{sub 3}. The pH of the bath was kept constant at 8. The potassium carbonate (K{sub 2}CO{sub 3}) was added into electrolyte to promote the detachment of anodic ZrO{sub 2} film from the underlying zirconium (Zr) substrate. The poor adherence of ZNTs layer was due to generation of CO{sub 2} gas that was thought to occur between metal|oxide interfaces. The effect of anodization voltages towards the detachment of ZNTs layer was systematically studied at 20 V, 40 V, 50 V and 60 V for 1 hour. The formation of CO{sub 2} gas is a function of anodization voltage, in which at 60 V, a good anodic film separation seen due to higher formation of CO{sub 2} gas. A preliminary study shown the capability of ZNTs in removing 5 ppm of Cr(VI) aqueous solution under illumination of UV light.
