Recubrimientos porosos de dióxido de titanio sintetizados por oxidación anódica

ABSTRACT Titanium dioxide is one of the most used materials in heterogeneous photocatalysis due to its commercial availability, low cost, chemical stability, low toxicity and high photocatalytic activity. One of the most efficient and economical methods to obtain TiO2 coatings is the plasma electrolytic oxidation. In this anodization process, a direct current is circulated between a cathode and an anode immersed in an electrolyte solution, at a high voltage that induces the formation of spark discharges on the surface of the anode. In the present work, porous TiO2 coatings were obtained by pla...
