Abstract:

A novel strategy involving the combination of soft-templating and the solid-liquid method (CSSL) is presented for the synthesis of mesoporous nanocrystalline zirconia with a high specific surface area. The mesostructured zirconia hybrid is firstly synthesized by the soft-templating method using 1-hexadecyl-3-methylimidazolium bromide (C16mim+Br-) as the structure-directing agent and zirconium sulphate as an inorganic precursor. It is then ground in the presence of solid copper nitrate followed by heat-treatment in air. The resulting zirconia material, after calcination at 600 ℃, possesses a wormlike arrangement of mesopores surrounded by tetragonal ZrO2 nanocrystallites of ca 2.50 nm diameter. The Brunauer-Emmett-Teller (BET) surface area is 240.0 m2·g-1 and the pore size is 4.10 nm. However, no mesoporous structure exists in the obtained zirconia material that was produced using the simple soft-templating method at the same calcination temperature. The BET surface area is only 9.5 m2·g-1 for this material.
