【摘要】 研究了合成条件对制备多孔阳极氧化铝膜（AAO）的影响,电压和电解液温度对AAO的形成及孔径的有序度影响显著,40V电压下模板孔的规则性及有序性较优;电解液温度不宜超过25℃;二次阳极氧化及适当扩孔比一次阳极氧化制备的AAO的孔更规则有序。以AAO为模板,采用溶胶-凝胶法沉积铁盐至AAO孔道中,再经高温焙烧制得氧化铁纳米线,其主要组成为非晶态的γ-Fe₂O₃,且其尺寸受限于模板。更多还原

【Abstract】 The conditions for preparation of porous anodic aluminum oxide template（AAO） was studied in this paper.Anodic voltage and electrolyte temperature had great influence on the surface morphology and pores diameter of AAO.The electrolyte temperature should be under 25℃.The holes in the synthesized AAO obtained by the two-step anodization and then reamered were more ordered than those by the one-step anodization.Moreover, Iron oxide nanowire was obtained by using the sol-gel method with AAO as template.The main composition of iron oxide nanowire was amorphousγ-Fe₂O₃ and the its size was limited by the AAO template.更多还原
