Abstract
La presente invención se relaciona con un material semiconductor de titania nanoestructurada, denominado TSG-IMP, y su proceso de obtención vía el método sol-gel. El material semiconductor TSG-IMP está constituido básicamente por óxido de titanio, con la característica especial de encontrarse como nanoestructuras, lo que le confiere propiedades fisicoquímicas especiales, con capacidad para dispersar y estabilizar partículas metálicas con una alta actividad y selectividad en procesos catalíticos principalmente. El proceso de obtención del material semiconductor TSG-IMP consiste en la adición, a un sistema de reflujo con agitación constante, de un alcóxido de titanio a una solución alcohólica; adicionar un ácido a la solución alcohólica, controlando el pH de 1 a 5; someter la solución en medio ácido a condiciones de agitación y reflujo a una temperatura de 70 a 80 °C, estabilizar el medio y proceder a la adición de agua bidestilada, en una relación molar agua/alcóxido de 1-2/0.100-0.150, continuando con el reflujo hasta la formación del gel; someter el gel a un tratamiento de añejamiento, por un tiempo de 1 a 24 horas, para la total formación de la titania; secar la titania nanoestructurada a una temperatura de 50 a 80 °C, durante un tiempo de 1 a 24 horas; y someter la titania seca a una etapa de calcinación a una temperatura de 200 a 600 °C, durante un tiempo de 1 a 12 horas. La dimensión del tamaño de cristal de las nanoestructuras de la titania del material semiconductor TSG-IMP depende del manejo particular o en conjunto de las variables del método sol gel, tales como los tipos de alcóxidos metálicos de titanio utilizados, las características de los solventes, la relación alcóxido/agua, y el medio en el cual se lleva a cabo la hidrólisis, que puede ser ácido o básico.
