摘要
A method, whereby metal ions and precipitation reagents were transported in the nanochannels of anodic alumina membrane (AAM) templates by converse diffusion or convection and reacted in situ to form into one-dimensional nanostructure of the precursor, was developed. A high-aspect ratio nanowire array of the LaMnO3+delta was prepared by this method. Electron microscope images showed that the LaMnO3+delta nanowire array was abundant, uniformly distributed and well-ordered in large area. The individual nanowires are about 60 nm in diameter and their length corresponds to the thickness of the applied AAM template. The analysis of X-ray diffractions demonstrated that the LaMnO3+delta nanowires are pseudocubic with typical perovskite lattice parameter. (c) 2005 Elsevier Ltd. All rights reserved.
