低温水溶液系统合成磷酸铈纳米线

Study on Synthesis of Cerium Phosphate Nanowires from Aqueous Solutions under Environmental Conditions

在低温水相体系中,无表面活性剂或模板存在,合成磷酸铈(CePO4)纳米线。采用XRD、SEM、TEM、FT-IR和荧光分光光度计对所制样品进行表征,结果表明,控制水浴温度、陈化时间、反应物浓度可以控制CePO4纳米线的长宽比和形貌。这项研究,为磷酸铈纳米线的规模化生产提供了可能。

In low-temperature aqueous system, cerium phosphate nanowires were synthesized without the presence of surfactants or template. X-ray diffraction （XRD）, scanning electron microscopy （SEM）, transmission electron microscopy （TEM）, FT-1R spectrometer and fluorescence spectrometer were applied to characterize the as-prepared samples. Results show that aspect ratio and morphology of cerium phosphate nanowires can be managed by controlling reaction temperature, aging time. and concentration of reactants.
