Ordered iron nanowires in the mesoporous silica matrix

Abstract We report a novel synthetic method for preparation of ordered magnetic iron nanowires in mesoporous silica matrix. The method is based on the incorporation of a hydrophobic metal compound, Fe(CO)5, into the hydrophobic part of a freshly prepared mesoporous silica–surfactant composite. Shape and size of obtained iron nanowires is consistent with the dimensions of porous framework. Particles are uniform and well ordered in the silica matrix. Thus, mesoporous silica serves as nanoreactor for the formation of Fe-nanoparticles.
