Modificación de placas de concreto con tio2 para la degradación fotocatalítica de contaminantes líquidos
Abstract
Placas de concreto fueron impregnadas con TiO2 mediante dos métodos de soporte: painting coating y deposición de una mezcla de cemento gris y TiO2, Degussa P-25. El primer método consistió en la aplicación de un sol-gel de TiO2 formado a partir de tetraetilortosilicato, isopropanol, agua y ácido clorhídrico. Las propiedades fisicoquímicas de los nuevos materiales fueron determinadas usando Microscopía Electrónica de Barrido, Espectroscopía Infrarroja y de Reflectancia Total Atenuada, pruebas abrasivas, erosivas y fotoquímicas. Las películas obtenidas fueron estables, consistentes, con una buena distribución del semiconductor y con una actividad fotoquímica superior a la del concreto común.Downloads
