Homogenous, transparent, monolithic and red titanium hybrid gel was obtained by reaction of homogenous mixture of titanium butoxide Ti(OBun)(4) with the aromatic ring (1,4-dihydroxybenzene HO-C6H4-OH) (DO1,4) in n-butanol at room temperature, without the addition of catalyst and water. Infrared spectroscopy was used to characterize the obtained material. The results show that 1,4-dihydroxybenzene reacted with the titanium alkoxide leading to the transparent monolithic and red gel in which both organic and inorganic -Ti-O-C6H4-O-Ti-bridges are formed. The thermal analysis of the xerogel was determined by TGA and DTA. The morphology, texture and structure of the material were studied by scanning electronic microscopy (SEM), Brunauer-Emmett-Teller (BET) method and X-ray powder diffraction (XRD). The X-ray diffraction pattern of the material calcined at 600 degrees C is consistent with the formation of TiO2.
