Efecto de fotodegradacion producido por recubrimientos de ti o 2 y ti o 2 si o 2 obtenidos por sol gel
Abstract
El método sol-gel es adecuado para la fabricación de sistemas binarios, con propiedades de interés a nivel industrial. Al adicionar SiO2 a un sistema de TiO2, las propiedades generales de este último se verán modificadas. En el caso de las propiedades fotocatalíticas, la adición de un 30% de SiO2, afecta significativamente el comportamiento de este sistema aún si se compara con otro al que se ha adicionado solo un 10% de este óxido, haciéndolo mas eficiente en los procesos de fotodegradación del azul de metileno, presente en una solución de 3.5mM. Este efecto se estudio, analizando el espectro de absorbancia de una solución de azul de metileno, concretamente a 665nm, donde esta presenta su máximo de absorbancia.Downloads
