摘　　要：以5%磷酸为电解液,采用二次阳极氧化的方法制备了氧化铝多孔模板,利用扫描电子显微镜(SEM)对它进行表征,并对反应机理进行了探讨和研究,结果表明纳米孔洞是由于铝表面氧化层的生成和电解液界面氧化铝的溶解两个过程相互竞争生成的.The phosphoric acid of 0.5 % was used in our experiments, the preparation technique of aluminum oxide template by two-step anodic oxidation was introduced and tested with SEM. We thought that the nano-sized pore on the Al surface were governed by the competition of formation and dissolution of alumina film during the reaction process.
