A novel one step gas phase synthesis method for hollow SiO2 nanospheres under ambient condition was developed using an electron beam irradiation system. Ag nanoparticles were used as a guest-template material. The inner structure of the hollow SiO2 nanospheres can be controlled by adjusting the electron beam intensity and precursor concentration. The average diameter and shell thickness of the produced particles were 56 nm and 10 nm, respectively.



Keywords: Hollow SiO2 nanosphere; Electron beam irradiation; One-step gas phase synthesis.
