Abstract: The polyoxometalate particles with Keggin structure, (NH4)3PMo12O40 ·9H2O(1) and (NH4)3PW12O40 ·7H2O(2), were prepared firstly by solid state reaction at room temperature. Their structure, particle sizes and appearances were characterized with elemental analyses, IR, XRD and TEM techniques. The size distribution of nanoparticle 1 is in the range of 5—14 nm, the mean size is 9 nm, and the size distribution of nanoparticle 2 is in the range of 3—12 nm, the mean size is 6 nm. It was found that the product H2C2O4·2H2O plays a critical role in preventing the nanoparticles from aggregating to large particles.
