摘要
以汞为介质,通过铝的催化氧化反应制备出氧化铝纳米线．采用FE-SEM、TEM、EDX、XRD, IR等手段对氧化铝纳米线进行表征．结果表明,氧化铝纳米线直径为5～15nm,无定型结构．随着反应温度、铝纯度、反应气氛中的氧含量升高,氧化铝纳米线比表面积增大;HgCl2溶液浓度、铝浸入溶液的时间对氧化铝纳米线的比表面积没有明显影响．
Alumina nanowires, amorphous, with diameters from 5 to 15nm, were prepared by catalytic oxidation with mercury as medium. FE-SEM, TEM, EDX, XRD, IR were used to characterize alumina nanowires. With elevation of temperature, oxygen content and purity of aluminium, the alumina nanowires＇ specific surface area increases. The concentration of HgCl2 solution and the immersing time of aluminium have no apparent influence on alumina nanowires＇ specific surface area.
