Research output: Contribution to journalArticlepeer-review


A gel was formed when a mixture of TiOCl2 and citric acid is heated on a water bath. An ultrafine powder of TiO2 in the anatase phase is formed, when the gel was decomposed at 623K. The anatase phase is converted into rutile phase on annealing at higher temperatures >773K. These powders are characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and surface area measurements. The average particle size obtained for anatase phase is 3.5nm whereas it is 45nm for rutile phase.
