| 摘要: 室温下1.5 mmol·L-1硫酸铵溶液体系中，以阳离子型表面活性剂十六烷基三甲基溴化胺为模板，四水硫酸锆为无机前驱体，按照配位体辅助模板机理合成介孔氧化锆前驱体。通过液相后移植工艺实现了钙对氧化锆的掺杂改性。借助XRD、TEM、UV-Vis、XPS、N2吸-脱附及室温荧光光谱(RTPL)等方法对样品进行了表征分析。研究表明，钙离子进入氧化锆骨架结构中，掺杂改性后的氧化锆具有很强的荧光特性，其孔径尺寸在2.2 nm左右。 |

| Abstract: Mesoporous zirconia materials were prepared under room temperature in 1.5 mmol·L-1(NH4)2SO4 aqueous solution by the sufactant-assisted route, using a cationic surfactant(cetyltrimethyl-ammonium bromide, CTAB) as the template and Zr(SO4)2·4H2O as the precursor. The calcium was incorporated by grafting method. XRD, TEM, UV-Vis spectroscopy, XPS, Nitrogen adsorption and Room temperature fluorescence spectroscopy(RTPL )were adpoted to characterize the microstructure and properties of the synthesized materials. Results showed that a small amount of calcium had been incorporated into the framework of zirconia, and the powder exhibited strong fluorescence character and maintained mesoporous structure with an average pore size of 2.2 nm. |
