摘要
以无水乙醇为溶剂,采用溶胶-凝胶法合成中孔氧化锆,对合成的样品进行低温N2吸附-脱附、X-ray粉末衍射(XRD)、傅立叶变换红外光谱(FT-IR)等表征。结果表明,溶胶-凝胶法可以制备出具有单一晶型的四方相中孔氧化锆,其比表面积(BET)72.98m2/g,孔径2.2nm。
Mesoporous zirconium oxide was synthesized by the sol-gel procedure in the solvent of absolute etha- nol. The resulting oxide was characterised with several tools： nitrogen adsorption-desorption isotherms, XRD, FT- IR measurements. The results showed that the phase structure of ZrO2 is mesoporous tetragonal system,with BET specific surface area and pore diameter of about 72.98m2/g and 2.2nm respectively.
