Abstract
One embodiment of the present invention is a hollow silica nanomaterial (HSN). The HSN includes silicon dioxide (SiO) molecules which join together to form a shell. The shell extends from a first end to a second end and has a generally circular cross section, an inner surface and an opposite outer surface. Another embodiment of the present invention includes a method for forming an HSN. The method includes combining polyvinylpyrrolidone (PVP) and an alcohol to form a mixture, adding water to the mixture, adding sodium citrate to the mixture, adding a silicon-containing compound to the mixture, adding a catalyst to the mixture, and collecting hollow silica nanomaterials.
