Zirconia has attracted much attention as catalysts and catalyst supports. One of the challenges in the synthesis of zirconia is to create high specific area with thermally stabile tetragonal structure. So far most reports concentrated on the sol-gel process combined with self-assembly of various surfactants. However, an inherent drawback of these materials is the facile loss of surface area with increasing temperature, especially at temperatures higher than 400 °C. In the present work, a simple carbon templating method was studied for preparation of mesoporous zirconia with a tetragonal structure. Surface area was more than 100 m2/g even after calcination at 823 k for 10 hrs.
