摘要：
WO3 center dot H2O nanoflowers assembled of nanoplates were synthesized through the method of water bath with the assistance of oxalic acid. The effect of oxalic acid on tailing morphology was investigated through XRD and SEM analyses in detail. The results show that when the ratio of oxalic acid to sodium tungstate is 1.6, the obtained nanostructure is nanoflowers, which have smooth surface, regular edges and well crystallinity. Combined with the results of SEM observation, the evolution mechanism from nanoplates to nanoflowers was schematically presented and discussed. The preparation and mechanism of WO3 center dot H2O nanoflowers hold great potential for the syntheses of nanostructured MOS materials in low spending and their application.
