摘　　要：以P123为致孔剂,氧氯化锆为锆源,无水乙醇为溶剂合成前驱体,采用压力诱导的方法将前驱体注入到阳极氧化铝(AAO)模板的纳米孔道内,经加热处理后,在模板的纳米孔道内合成了具有介孔结构的一维ZrO2纳米材料;并用SEM、TEM、XRD、EDS和氮气吸附-脱附等方法对ZrO2进行了表征。结果表明:所合成的ZrO2纳米线直径约为60nm,各纳米线单元由分布均一、孔径约为8nm的介孔结构构成,比表面积为121.6m2·g-1,并且具有良好的光致发光性能。The precursor was prepared using P123 as porogen, ZrOCl as zirconium source and ethanol as solvent, then assembled into nano-channels of anodic aluminum oxide （AAO） templates by vacuuming and pressure induced technology. After heat treatment, one-dimensional ZrO2 nanomaterials with mesoporous structure were fabricated within the nano-holes of AAO templates. The obtained samples were characterized in detail by SEM, TEM, XRD, EDS and N2 sorption and desorption. The results show that the synthesized ZrO2 nanowires were 60 nm in diameter, 121.6 m2 ~ g ~ in specific surface area, had a homogeneously distributed mesoporous structure with pore diameter of 8 nm, and owned good photoluminescence property.
