TiO2 sintetizado por el método de precursor polimerico (Pechini): estructura de la resina intermedia

Abstract

En este trabajo se ha utilizado el método de precursor polimérico (método de Pechini) para sintetizar dióxido de titanio, proceso que ha permitido tener un mayor control sobre la pureza del óxido y el tipo de fase que ha presentado el material obtenido, fase anatasa en el presente caso. Durante el proceso de síntesis se ha obtenido una resina que se ha caracterizado utilizando la espectroscopia de Resonancia Magnética Nuclear (RMN) y la espectroscopia infrarroja con transformada de Fourier (FTIR) para determinar su estructura y con base en ella se ha propuesto un modelo para la conformación de la misma. Posteriormente esta resina se ha sometido a un tratamiento térmico para obtener los polvos cerámicos que se han caracterizado empleando diferentes técnicas, principalmente, difracción de rayos X (DRX) y microscopia electrónica (MET y MEB). Los resultados indican que se puede obtener TiO2 fase anatasa a los 450ºC con un tamaño de partícula <100nm.
