We proposed a general hydrothermal strategy for the fabrication of one-dimensional cadmium hydroxide nanostructures. Through controlled experimental conditions, such as solvent properties, salt concentration and alkaline concentration, the different morphologies and dimensions of the final products have been controlled. With this method, Cd(OH)(2) nanowires were prepared readily. XRD, TEM, FESEM and UV-vis absorption spectroscopy were used to characterize the nanowires product, which revealed that the Cd(OH)(2) nanowires consisted of about 30 nm in diameter and length up to several hundreds of nanometers. The optical absorption spectrum indicates that the Cd(OH)(2) nanowires have a indirect band gap of similar to 2.56 eV. In addition, the as-prepared Cd(OH)(2) nanowires acting as a precursor was converted into porous cadmium oxide through dehydration. (C) 2009 Elsevier Masson SAS. All rights reserved.
