摘要：

Novel binary tin-doped porous zirconia has been prepared by using zirconyl chloride, tin chloride as Zr, Sn sources and cetyl-trimethylammonium bromide (CTAB) as template. For the first time the hexagonal and ordered porous zirconia with a tin/zirconium molar ratio of 0.05 and 0.10 were obtained. The surface areas of the materials were 391.5 and 501.5 m(2)/g respectively. Thermal stabilities of the prepared samples were relatively high (>773K) and decreased with the increment of tin content.
