Using polyvinyl alcohol(PVA) and sodium dodecyl sulfate(SDS) as the surfactants respectively, nano-size amorphous molybdenum dioxide powders were prepared by y-radiation method at ambient pressure and room temperature, and the products were characterized by use of laser Raman spectra(LRS), X-ray powder diffraction(XRD) and transmisson electron micrograph(TEM). The experimental results reveal that the relative pure satnples can be obtained using PVA as surfactant, and the average particle size is about 10nm, but using SDS as surfactant, the samples with the average particle size 30nm are a mixture of MoO2 and MoO3. This suggestes PVA is prior to SDS in the preparation of nano-sized amorphous molybdenum dioxide powders by γ-radiation method.
