Abstract

Nanostructure SiO2 was prepared from mealies corns. The micron phytoliths were obtained after treatment with mixed acids, using the phytolith samples as raw materials, nano-silica was obtained through calcining at certain temperature after boiling in the nitric solution. And its structure was characterized by X-ray diffraction (XRD), optical microscope, transmission electron microscope (TEM), scanning electron microscope (SEM), energy dispersive spectroscope (EDS) and Infrared Spectroscope (IR). The results show that the phytoliths are all dumbbelltype in cornstalks and leaves in the micro level; however they are located along or against vertically the lignose, respectively. The nanosilica with diameter of 103nm is obtained through calcination after boiling in HNO3 solution, and the nano SiO2 crosslink in higher temperature.

Key words： phytoliths; mealies corns; nano SiO2
