Studies on TiO2 ceramic membranes prepared by electrolytic method

Résumé

TiO₂ microporous membranes were prepared on graphite support by an electrolytic method using an alcoholic solution of TiCl₄. After electro-deposition, the samples thus obtained were allowed to dry in air atmosphere at room temperature and were subsequently heat treated to 400oC for 4 hours. Optical microscopy (OM), X-ray diffraction, thermal gravimetry, differential thermal analysis and nitrogen adsorption method were used to investigate structure and morphology of TiO₂ membranes. The results show that the membranes thus obtained shows a porosity that decreases increases with temperature, while the average pore size results show that the membranes thus obtained shows a porosity that decreases with temperature, while the average pore size increases.
