Advances on the synthesis of porous TiO2 coatings by anodic spark oxidation : photocatalytic reduction of Cr(VI)
(Elsevier, 2017-04-15)Porous TiO2 coatings were obtained by anodic oxidation in spark discharge conditions, varying the range of current density (200–3000 A m−2) and the electrolyte concentration (H2SO4; 1 and 4 M). The samples were characterized ... -
Heterogeneous photocatalytic Cr(VI) reduction with short and long nanotubular TiO2 coatings prepared by anodic oxidation
(Elsevier, 2018-01-01)Nanotubular TiO2 coatings prepared by anodic oxidation of titanium were evaluated for the first time in the photocatalytic Cr(VI) reduction in the presence of EDTA. Small nanotubes (SN) were prepared by using aqueous ... -
Recubrimientos porosos de dióxido de titanio sintetizados por oxidación anódica
(Universidad Federal de Rio de Janeiro, 2018-07-19)El TiO2 es uno de los materiales más utilizados en el proceso de fotocatálisis heterogénea debido a su disponibilidad comercial, bajo costo, baja toxicidad y elevada actividad fotocatalítica. Uno de los métodos más eficientes ...
