摘要
Mesoporous tetragonal sulfated zirconia with high surface area and narrow pore-size distribution was prepared using Zr（O-nPr）4 as zirconium precursor, sulfuric acid as sulfur source and triblock copolymer poly（ethylene glycol）-poly（propylene glycol）- poly（ethylene glycol） （P123） as the template. The samples were characterized by X-ray diffraction, N2 sorption, TEM, and NH3- TPD. A phase transformation from monoclinic sulfated zirconia to tetragonal sulfated zirconia is observed. The product shows strong acidity.C2009 Bin Yue. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
