摘　　要：ent, the size distribution and the micro structure of TiO2 on the cross section of Nafion membrane were discussed. Result s show that the quantity of Ti(OBu)4 and TiO2 in Nafion depends on the soaking solvent. A correlation between the water content in Nafion and the quantity of T iO2 formed was observed. However, the morphologies and the grain size distributi on of nanocrystalline TiO2 in Nafion was not influenced by the water content in Nafion. EDAX analysis indicated that the line and surface distribution of every element content on the cross section ofHighly ordered iron oxide nanowire arrays were prepared by sol-gel template method within the pores of anodic alumina membrane (AAM). Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD) were used to characterize the morphology and crystalloid structure of iron oxide nonawire arrays. It was demonstrated that iron oxide nonawires were very uniformly assembled and parallel to each other as the pores in AAM template. The length and diameter of nanowires were dependent on the thickness and hole diameter of AAM.
