One-pot Synthesis Of Nanotube-based Hierarchical Copper Silicate Hollow Spheres

摘要

A new type of hierarchical structure, copper silicate hollow spheres assembled by nanotubes, was synthesized via a simple one-pot route by using silica colloidal spheres as chemical template.rnHollow spheres have attracted much attention because of their potential applications in catalysis, delivery vehicles, photonic materials, optics, sensors etc. Various approaches have been used to synthesize hollow spheres, such as hard or soft templa-ting methods, and novel mechanisms like Ostwald ripening and the KerKendall effect were also introduced to fabricate hollow spheres. Recently, hierarchical hollow spheres with the shell constructed of many kinds of nanostructure including nano-bubbles or one-dimensional structures have been focused on for their structural characteristics, which endows them with a wide range of potential applications.
