摘要: Mesoporous tetragonal sulfated zirconia with high surface area and narrow pore-size distribution was prepared using Zr(O-nPr)₄as 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 showsstrong acidity.
