Over the last few decades, the sol-gel techniques have been used to prepare a variety of mixed-metal oxides, nanomaterials and nanoscale architectures, nanoporous oxides, organic-inorganic hybrids. These materials now represent one of the largest manufacturing sectors in the world. One challenge for the high end of the market is the development of alternative synthesis technologies that are not just “greener” but provide environmentally benign processes. It is well known also that physical properties of crystalline materials are strongly dependent on the phase purity, grain size and grain size distribution. Therefore, it is also very important to develop simple, reliable and cost-effective synthesis method for the preparation of products with controllable phase purity and surface morphology. Among different synthesis methods, sol–gel processing route is most convenient method because of its simplicity, good mixing of starting materials, relatively low reaction temperature and easy control of chemical composition of the end product. Sol-gel synthesis is utilized to fabricate advanced materials in a wide variety of forms: ultrafine powders, thin film coatings, fibbers, porous or dense materials. The scope of this Special Issue of Materials is focused on the development of sol-gel synthesis technique, and application of sol-gel processing for the fabrication of multifunctional materials, which are important in all industrial areas. The field of the research in the evolution of inorganic networks through the formation of a colloidal suspension (sol) and gelation of the sol to form three-dimensional, continuous network in a liquid phase (gel) is very much appreciated.

Title: Conversion of one-dimensional Ni/NiO core-shell nanowires to NiO nanotubes
Authors: Zibin Dong, Yi Luo, Weifeng Zhang, Haizhong Guo and Wenfeng Xiang
Abstract: Conversion of one-dimensional Ni/NiO nanowires to polycrystalline NiO nanotubes has been performed by a heat-treatment method. The microstructure and surface composition of the Ni/NiO nanowires and NiO nanotubes during the conversion were investigated employing a combination of x-ray diffraction, Raman spectra, scanning electron microscopy, transmission electron microscopy, photoemission spectroscopy, and x-ray photoemission. The results show that the Ni nanowires convert to Ni/NiO core-shell nanowires with increasing the annealing temperature and then completely convert to NiO nanotubes over 600 °C. The NiO grain size and NiO/Ni ratio increase, and the surface roughness of the Ni/NiO nanowires gradually decreases with the annealing temperature. Our findings demonstrate that the conversional evolution of the Ni-based nanostructures may provide useful information for the preparation of the one-dimensional Ni-based nanostructures with different microstructure and properties to meet their various applications.
