dc.description.abstractThe present work illustrates the great potentiality of Ti/TiO2/Sb2S3 composite electrode prepared by electrochemical anodization of Ti foil in aqueous electrolyte (1 mol L-1 NaH2PO4 + 0.3 wt.% HF followed by chemical bath deposition of Sb2S3) in environmental electrochemistry. The electrodes are characterized by deposits of particles of 500 nm of diameter formed on the top of TiO2 nanotubes of 900 nm of length, 110 nm of diameter and 13 nm of wall thickness. The band gap obtained for Ti/TiO2/Sb2S3 composite electrode was 1.68 eV, contributing to strong photoabsorption properties of the material in the visible light region (lambda <740 nm). The photocurrent on this material is remarkably improved in relation to that obtained on comparable nanotubes TiO2 films. The electrodes promote complete degradation of the investigated hair dyeing commercialized as ArianorTyrian Purple (R) after 120 min of photoelectrocatalytic oxidation under potential of 1.2V and commercial light irradiating under UV/Visible light. Finally, the degradation products generated by photoelectrocatalysis were analyzed by HPLC-MS/MS. (C) 2013 Elsevier B.V. All rights reserved.en
