Inorganic fullerenes and nanotubes: Wealth of materials and morphologies
Department of Materials and Interfaces, Weizmann Institute of Science, Rehovot, 76100, Israel
It is already well established today that numerous materials form closed-cage structures, of which carbon fullerenes and nanotubes are a special case . Inorganic fullerene-like nanoparticles (designated IF) and inorganic nanotubes (INT) have been produced by different routes and experimental techniques, achieving persistent growth of a variety of materials and structural wealth within them. The research in this area has focused on synthesizing new IF and INT materials and understanding their different properties as well as scaling up the synthetic process in order to make it suitable for industrial applications. In this review, the main synthetic procedures to obtain inorganic fullerene-like nanoparticles and nanotubes will be discussed alongside with the different mechanisms that affect the morphology of the final product. The main differences between the morphologies will be presented. Some general considerations relating the properties of the parent compound with the morphology of the product will be mentioned.
