【摘要】 以表面活性剂十二烷基磺酸钠为模板制备了含稀土元素La的无机-有机纳米复合材料。通过XRD、SEM、HRTEM、EDX等的表征,证明所得的稀土复合物为层状结构,且十二烷基磺酸钠与La的比例为1∶1。考察了反应温度、反应时间以及原料配比等对复合物结构的影响。更多还原

【Abstract】 A kind of inorganic-organic nanocomposites containing lanthanum was synthesized using the sodium dodecyl sulfonate as template. From the characterization of XRD, EDX, SEM, and HRTEM, the composites were found to be with a layered structure, and the molar ratio of S to La was 1∶1. The effects of molar ratio of the surfactant to the rare earth ions, reaction time and temperature on the layered structures of the composites were studied.更多还原
