Abstract

Pure brookite phase titania crystals with large surface area have been synthesized at room temperature by the Plasma Enhanced Chemical Vapour Deposition technique, using titanium tetra-isopropoxide vapour, argon and oxygen mixtures, deposited on silicon (100) substrates under an applied substrate d.c. bias voltage of −250 V. The X-ray diffraction analysis for the as-deposited titania has confirmed the crystallinity and phase as brookite titania. Scanning Electron Microscope micrographs show the morphology of the brookite titania crystals with largest lateral dimensions of about 500×1200 nm, i.e. relatively large surface area crystals. There are no reports on the preparation of brookite titania crystals with such large surface areas.
