Seeded growth of iron oxide onto titanate nanowires
Résumé
The combination of different inorganic structures enables the preparation of multifunctional hybrid materials. The control on the formation of low dimensional nano-objects with specific morphologies and sizes is also a determinant factor to define specific properties. In this aim, the influence of the basic medium on hydrothermally prepared titanate nanowires was studied. The presence of Na+ or K+ counter ions dramatically influenced the preparation of nanoparticles or nanowires of TiO2 and titanate. In a second time, hybrid materials were prepared by the impregnation of the titanate nanowires by a solution of iron chloride followed by the addition of NaOH to induce the formation of iron oxide onto titanate nanowires by the co-precipitation method.
