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.
