Synthesis and Characterization of Iron Oxyhydroxide Nanowires

A very simple method of synthesis of goethite,alfa-FeOOH, nanowire is reported. To fabricate the nanowires, an anodiezed alumina nanoporous template (AAO) is used. AAO has pores with an average diameter of 60 nm. The synthesis is based on a self-combustion reaction of the chemical precursor (Fe(NO3)3 satured solution) which occurs inside the nanopores. The geometry of AAO determines the morphology of the nanowires and the conﬁnement conditions in which the heat treatment determines the composition of the nanostruc- ture. The nanowires are characterized using scanning electronmicroscopy, high resolution transmission electronmicroscopy andmagne- tometry [magnetization versus applied ﬁeld (M versus H)]. TEM analysis indicates that nanowires are composed of several alfa-FeOOH single crystals. The nanowires have a clear magnetic oriented structure.
