【摘要】 以多孔阳极氧化铝为模板,采用逆向迁移技术,在模板的纳米孔道内反应形成一维纳米结构前驱体,再经后续处理,制得了Sr2CeO4纳米线。通过X射线衍射光谱(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)等检测手段对产物进行了表征,结果表明,所得Sr2CeO4纳米线阵列排列整齐,单体纳米线的直径大约为60nm,与所用模板的孔径相当,长度可达30μm。

【Abstract】 Ordered Sr2CeO4 nanowire arrays embedded in anodic alumina membranes(AAM) were fabricated by a converse transport technique that precipitations were shaped into one dimension structure in the hexagonally ordered nanochannels of the AAM and changed into the Sr2CeO4 nanowire by the subsequent treatment.The nanowires were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),the transmission electron microscopy(TEM).The TEM images showed that Sr2CeO4 nanowires were about 60 nm in diameter and up to 5μm in length,which correspond to the pore sizes of the applied membranes.The SEM images showed that the Sr2CeO4 nanowires were abundant and uniform.
