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 ...
Influencia de los tratamientos térmicos en recubrimientos anódicos nanotubulares de TiO2Influence of thermal treatments in nanotubular anodic coatings of TiO2
(Universidad Federal de Rio de Janeiro, 2018-07-19)
El TiO2 es un semiconductor ampliamente utilizado en el proceso de fotocatálisis heterogénea para la des-contaminación de aguas. Diversos estudios indican que las estructuras ordenadas de nanotubos en fase ana-tasa mejoran ...
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 ...
Influence of the electrolyte concentration on the smooth TiO2 anodic coatings on Ti-6Al-4V
(MDPI, 2017-03-03)
To obtain smooth TiO2 coatings for building a new design of Ti-6Al-4V heart valve, the anodic oxidation technique in pre-spark conditions was evaluated. TiO2 coating is necessary for its recognized biocompatibility and ...
Synthesis and morphological characterization of nanoporous aluminum oxide films by using a single anodization step
(MDPI AG, 2019-02-13)
Nanoporous anodic aluminum oxide (AAO) films play an important role in nanotechnology due to their easily adjustable morphological properties and wide range of applications. Thus, a deep and systematic characterization of ...
