Efectos de fotodegradación propiciados por recubrimientos de TiO<sub>2</sub> y TiO<sub>2</sub>-SiO<sub>2</sub> obtenidos por Sol-Gel

Abstract: El efecto de fotodegradación es ampliamente utilizado para la purificación del agua, acción que contribuye a la conservación y protección del medio ambiente; el óxido de titanio (TiO 2 ) es uno de los semiconductores que pueden degradar contaminantes mediante procesos de oxidación, lo que lo hace apto para el tratamiento de aguas residuales. En este trabajo se conformaron recubrimientos de TiO 2 y TiO 2 -SiO 2 , por el método Sol-Gel, y se estudio la degradación que experimentaba una solución de azul de metile… Show more

“…The results in the present paper are a continuation of our work presented in [10], in which porous and biocompatible coatings obtained on Ti6Al4V alloy biomaterial, enriched in bactericidal copper [33][34][35][36][37][38] and depleted in vanadium and aluminium ions, were described. In this article, the authors present the PEO coatings obtained on another very popular alloy, i.e.…”

“…These binding energies provide the information to assume in fact the presence of titanium phosphate Ti–PO x within some non‐stoichiometric oxide TiO x in the surface layer . The high‐binding energy can be also partly explained by the Ti–N compounds present in the surface structure, which is composed predominantly of titanium and copper phosphates as well as by the existing compounds such as Ti–C . On the basis of P 2p spectrum, where the maximum is observed at 133.8 eV, one can assume the presence of titanium and/or copper phosphates in the PEO coating.…”
