In this paper, silicon oxide nanowires with P2(1)2(1)2 space group were synthesized by liquid-solid phase hydrothermal method, using silica sol, Fe ( NO(3))(3)center dot 9H(2)O and ethylenediamine-water solution as raw materials. Their structures were characterized by SEM, TEM, XRD and EDS. It was found that the reaction activity could be Improved due to the employment of suitable silica mid iron resources. As a result, the reaction conditions became more moderate, and less Fe species was used. An optimum experimental condition could be obtained, that is, the Si/Fe molar ratio of 1 : 0. 4, the ethylenediamine/water volume ratio of 8 : 5 the temperature of 180 degrees C and the reaction time of 4 d. This approach expected to provide a huge possibility for the industrialized manufacture of silicon oxide nanowires.
